1934-1940 Horn

[JTR249]

Can you tell from the inside if the face is original? This one has the stamp on the edge.

I believe it is original. I have one just like it.

Thanks, motor. Another member discussion made reference to even some reproduction faces having the bottom center stamp and I was wondering how they could tell the difference.

the inside face and mounting ring surface dont look 80 plus years old to me.
Also the mount holes seem to have been off,resulting in some wollowing out of the holes to fit,which would suggest non factory precision.
The body looks like a powder coated original
I have a Roger long example that is very similar,Kiwi face and original body powercoated.

It looks like the one I have on my bike (not correct for a 46) been on the bike since 79 or 80. Only difference I see is the rivet? at the base I don't think mine has that. Perhaps at some point your face was re-chromed?? Roger long rebuilt mine shortly before he passed as it had stopped working and one the studs on the back was always in rough shape.

...were original faces made of brass, chromed or nickel plated? If so, a magnet will uncover what's there.

also look at this: https://forum.antiquemotorcycle.org/...torcycle-horns

Joe's thread on these is the post I read to educate myself. I agree with you on the horn. No question there. I also noticed the holes, but wasn't sure.
Thank you all for the comments.

"look at this"
Okay Harry if I catch a cold . . . after reading the link (Thank You) you've got me trudging out to the barn in a snow storm. No writing on the bottom of mine but there does appear to be a screw where JRs' has a rivet. Will take a magnet with me next trip.

Here is an original horn….

No patent writing. Original faces are brass, and tend to have cracks around the outer diameter as can be seen in the pictures. I think this is caused by work hardening from the stamping process and residual stress aver the last 80 or 90 years.

this particular horn has the flat back cover, so 1938 1939 or 1940

JR, as to the question if your face is original I won’t pass judgement but show a comparison, I have a repop face I think from Greer

As you can see it has the patent stamp

here is the original face

The flange on the back is a bit wider then the original.

Also, the face is slightly magnetic, which makes me think it’s stainless steel.

[FLFD7]

A bit off topic but you might have noticed that the flange on the repop face is not drilled for the mounting screws. I had to figure out a way to hold the face flat so I can properly drill the holes, obviously couldn’t just push the Indian face into the drill press table, and I needed a way to locate and clock the holes. At work I have access to a 3d printer and this is what I came up with.

IMG_6071.jpeg I made a base to locate along the outside lip of the horn face and keep the face off the table. I made a cover with a lip that goes inside the mounting flange and has pilot holes for the drill, there is a reference mark to line up with the indians nose, and holes for the clamp screws.

once all snugged of I can drill my pilot holes, I made a second top cover with tap drill sized holes, and I’ll be good to go.
