Need info on Stahl's engine.

[crowskee]

I'm guessing this was made by C.V.S., Stahl's Motor Works, from my google research. I have found very little information and zero pictures of any bike or engine the company put out. Does anyone have any info on this?

There is a listing for Stahl motorcycles in the Encyclopedia of the world's Motorcycles:

STAHL(America 1910-1914)
Built in Philadephia, the Stahl motorcycles had a 4-5 hp single cylinder, and 7 hp twin engines.

I don't see any valve assemblies, or timer. Is that a blanking plate on the top of the cylinder?

[crowskee]

Yes it is a plate. I bought it off ebay. It was listed as an antique air compressor pump, seems someone had removed the head and put a plate in its place with a fitting threaded into to pump air. Its on its way to me on the Big Brown truck as we speak.

How goes it with the stahl motor. ? Have you found any other info ? Or parts?

[crowskee]

Found nothing so far other than they were made in Philly from 1910 to 1915. I got a Hedstrom head on it now but can't locate a cam gear to have it running. I'm starting to think its the last one in existence!

There was one that sold at the big Nebraska auction in the early 90's. If I remember it was a gentleman named Leo Bongers that owned the stuff. Lots of old cars and bikes. Back then I thought the Stahl was a 5 or 6 grand bike, it sold for 24 k, if I remember correctly. That day the 1907 Harley sold for $140,000 and pushed everything else at the auction to the moon. Then the same one resurfaced just a few years ago, I think it ended up at The National Motorcycle Museum in Anamosa, Iowa.

Not the same Dave,The Anamosa bike is an OP '08 that came from Dave Ohrt.From Illinois originally.John bought it from auction in vegas when Dave sold it...good friends needed to know value for sale?350K.The Nebraska OP'07 bike went to EJ Cole in Texas,sold last year

Not true. Ohrt never auctioned the 08 that parham owns. It was a private sale. As for the cv stahl, it was originally sold at the bonger auction, then changed hands two more times to reside in parhams museum for several years until last week when it changed hands again. It is a neat bike, and the only complete example I am aware of.

[silentgreyfello]

As for the motor pictured here in this thread, that looks earlier and smaller than the one that was at parhams museum. I think stahl built motorbikes and motorcycles about 1902-1912. They used the name cvs, then later cv stahl. The early bikes were a diamond frame, and they would sell motors to go into bicycles as well. Later 1910-1912 models were loop frames with bigger motors and could be single cylinder or twins. One that my friend just bought was the later single, and says "cv stahl" on the crankcase.

[crowskee]

The back crankcase on this engine says C.V Stahl across it.

Not sure how to upload pictures of similar engine that I have.

[Steveland]

Ok, Figured out how to ad pictures. Mine is quite similar. This is a massive engine and seems to be earlier then the engine in a circa 1911 CV stahl that I've seen pictures of recently (maybe either pacer or racer). Mine also has remnants of a Curtis carburetor, which I suspect would make it earlier as well. Doing research recently I ran across mention of engines as early as 1906 that were made for fitting into diamond frames. I believe thats what this is. Mine still has the frame brackets attached and seems like it would fit into diamond frame (A large diamond frame!). I live just a few blocks from Diamond St where these were made and had to have it, In fact, I did a trade with Harry Buck that included the rear wheel of the Killinger and Freund to own this baby years ago. Unfortunately, he didn't know anything about it's history. It's really interesting to see another similar engine. Some day I hope to find a suitable frame! Any more info on these Early C V Stahls would be appreciated!
