    Answer to my own question

    I can now answer my own question

    Year Engine number
    1914 50000 ->
    1915 63500 ->
    1916 75000 ->
    1917 88200 ->
    1918 93375 ->
    1919 97373 ->
    1920 103500 ->

    1923 108500 ->
    1924 108800 ->

    My engine number is 107841, and I therefor have an Excelsior produced in 1921.

        Henderson Motor Numbers

        Regarding your posting of Hen motor #s, in case you didn't know those #s were originally compiled by a Hen dealer and after market parts supplier named Ballock (Balock?) from St Louis. It needs to be pointed out as time passes, things like this get adopted as undisputable fact. Unfortunately, there doesn't seem that a specific X/Hen factory #s list has survived or turned up. When the AMA bought the Schwinn archives, I believe some very knowledgable X/Hen enthusiasts looked for such a list and could not find it. However, I do think the list you quote is fairly accurate at least after 1918 when Schwinn was fully in control of Hen production and particularly good for Deluxe and KJ/KL units. I do not believe the Detroit Hen #s to be fully accurate - note 1912,13 &14 are missing. Am interested if any other AMCA member can shed light on this with actual factory documentation (exclusive of Otis Spiker and the Henderson Restoral Society). I can't comment on the X numbers as I have not researched these machines to any meaningful extent.

        ps: I am also fortunate to have a very nice original unrestored 1924 big X. The 20 series Xs seem to be few in numbers.

          Excelsior Dating

          Happy New Year All.
          Whenever I encounter any data that assists in accurately dating motorcycles, I include it in a folder that contains dating data only.

          My query is, which published Excelsior figures are correct or put another way, the most accurate?

          The "Antique Motorcycle Magazine" Fall 1995 issue published figures for 1907 to 1914 Excelsiors with 1914 being engine #s
          48978 to 55909 but the data published in this post has the 1914 production starting at 50000 and going to 63499. Quite dramatically different numbers don't you think?

          Can anyone narrow down the production numbers, especially 1914, as the point that "scic" makes about a perpetuated myth is an extremely important fact and it is also important that people answering questions like this through the club magazine and this forum state to the viewers as to whether the information is proven facts or not.

          Regards Tommo
          I don't want to put the dampener on this site as I think it is excellent and it enables us on the other side of the world easy access to our fellow club members but I do feel every effort should be made to ensure we impart accurate and correct information.

            Yes, mis-information becomes fact over time. It's a huge revelation when you discover a bit of this, and want to share it with others.

            I think professional researchers include foot notes with sources of information. Pls correct me if I'm wrong, as to how they do it.

            I agree, it would be really nice if people would include foot notes, with sources to verify.

            Interesting how history sometimes gets rewritten.

            The tricky thing about our hobby is that a vast number of documents have been tossed or destroyed over the years. I feel doing the research is a big part of the FUN of the hobby. Hopefully this Forum will help members do some of this research/fact finding a little bit faster as a group.

            Side note: digital scanners are good. Silver gelitin photos fade (at 80-100yrs approx.), acid eats paper. If ya got it. Please scan it. ie. original factory photos/literature/blue prints/specs, etc.

              Excelsior numbers

              Hi again, and happy new year.

              My Excelsior/Henderson list is also published in the AMCA magazine. I don't know the year, or number but it is supplied by Bob McClean. The article is about Henderson Bill (called Introducing Henderson Bill) and on page 18 the Henderson and Excelsior lists are published. Before the lists it says:

              "Here's a little information for you Excelsior/Henderson fans. Bob McClean supplied this model and serial number list. Hurry.....Check your machine before the judges show up!"

              I am only interrested in a list that is correct, and if anyone owns a 1914 Excelsior it would be great if they could reveal the engine number of their bike. I have owned a 1917 Excelsior with the engine number 92110, and that is a perfect match with the list. I also have other friends stating that this list is correct compared to their engines. My only problem now is that I don't know what year my current Excelsior (107841) is produced. Untill I am proven wrong I will stick to the list and the year 1921.

              This forum should be perfect for joining all the Excelsior owners in the world and try to make a accurate list.

              Thanks again for having this forum, and I am looking forward to a lot of replys.

                Excelsior Dating

                Sorry Knut but I thought you must have had the 1907-1914 Excelsior production numbers that were published in the Fall 1995 issue of the magazine.

                They are;
                1907 000 - 289
                1908 290 - 835
                1909 836 - 3727
                1910 3728 - 9246
                1911 9247 - 15319
                1912 15320- 18063
                1913 18064- 48977
                1914 48978- 55909

                I don't know who supplied the above facts but I got them from a borrowed club magazine a few years ago.

                Using the above numbers gives the following production units so long as every available number was used.

                1907 289
                1908 546
                1909 2892
                1910 5519
                1911 6073
                1912 2744
                1913 30914
                1914 6932

                And then by using the figures you posted;

                1914 13500
                1915 11500
                1916 13200
                1917 5175
                1918 3998
                1919 6127
                1920 4000
                1921 500
                1922 500
                1923 300

                Juggling between the two different start numbers for 1914 can give other production figures for the 1914 /15 years.

                The higher production numbers for the 1914-15-16 years I suppose can be put down to the First World War effort but almost 31000 in 1913.
                Where did all the 1913 models go to, as by the law of averages they should be the most common surviving Excelsior.

                Back in the Winter 1980 issue of the club magazine a
                Mr Cliff Pease
                4164 Ewell Road
                Virginia Beach
                Va 23455
                was soliciting information for a Excelsior / Henderson Register.
                What has become of all the research notes he must have made?
                Was the Register ever circulated?

                Enough of my ramblings but as presented at present I feel the figures don't stack-up quite right with production numbers swinging up and down a bit too much.

                Those in the know please help?

                Yours in Motorcycling

                  Early Excelsior dating

                  A new found Excelsior friend tells me:

                  "Note that the serial numbers for singles and twins were not consecutive, I would assume the factory used "blocks of numbers" for the singles and twins back then."

                  This would make a difference when it comes to #'s. 1913 was the first year with 61ci (1000cc) only. Jerry Hatfield writes this in the book Antique American Motorcycle Buyer's Guide (on page 12). The V-twin was intorduced in 1910, and Excelsior had a two -model range in 1910, 1911 and 1912. The 1910 v-twin was 50ci (819cc). The v-twin from 1911 until 1921 was 61ci. From 1921 Excelsior also delivered an aditional 74ci v-twin.

                  How could I tell the difference without opening the cylinders and masure them?? On my 1928 HD JD I can count the ribs on the sylinder to tell.

                    Ribs

                    Hi again!

                    My 1921?? has 15 ribs on the cylinder itself, and 8 on the exhaust camber.

                      T3048

                      Tommo!

                      I have a problem. A friend of mine here in Norway owns a V-twin Excelsior with engine number T3048. He means that this is a 1912 model. This is all wrong again compared to your list. 3048 should be a 1909 model from your list, and 1910 was the first year with v-twins. Something is not right here. The register cover on his bike is not aluminum but nickel plated bronze.

                      I guess we just have to wait and see if other members are villing to unveil their engine numbers and years. I have already recived e-mails with engine numbers and production years from people that don't whant their bike ID to be published on this forum. That is perfectly OK with me. The important thing is to try to get a complete list that we can rely on.

                      I am looking froward to hear from you all on klund@loit.no

                        V-twins

                        Today I learned that Jerry Hatfield is wrong in his book, and singles was also produced in 1913 and 1914.

                        Engine 19795 is owned by Peter Dilworth (chunks23@hotmail.com), and this is a single (1913??). I have also recived e-mails from others telling me that they own post 1912 Excelsior singles.

                        I guess we just have to dig deaper into this. Please help me!

                          Excelsior motor numbers

                          I have my grandfathers 1915 Excelsior twin, with documentation indicating he purchased it from the factory in November 1915, calling it a 1915 model. Motor number is 77918. From Knut's list of numbers, this would be a 1916 model. So, what do I really have? bas2910@aol.com

                            Hi!

                            My best guess is that you have a 1916 model produced in 1915. Just like now you can buy a 2003 model car in late 2002.

                            I am just guessing over here, but I think it is a good one....:-)

                            If you post a picture of your bike it would be a lot easyer. There should be some differences to 1915 and 1916 (in the parts list the 1915 has it's own listing, while 1916 is combined with 1917).

                              1915 or 16??

                              Hi excel15,

                              Here is an easy way to tell if your X is a 15 or 16;

                              Look on the right side of the gas tank just behind the shifter. The 16 and later models have a petcock there with fuel lines running to the front and rear cylinders for cold start priming.

                              The 15 has just primer cups on the cylinders without the lines or valve on the tank, (and no provision on the tank for a valve).

                              Hope this helps!
