The images I received from John Koller , are for shure not from any Koehler-Escoffier.
By our first contacts, years ago, John Koller told me, the bike was sold to him, during his visit in France, as an Koehler-Escoffier, 500cc from 1912.
Because that model an brand is very rare to find,and as a member of the Monet Goyon, Koehler-Escoffier motorcycle club of France. (http://www.monet-goyon.net/) I was very interested to know al the details of this bike.
The only Koehler-Escoffiers from 1912 until 1920, where 500cc bi-cylinders in V.
After reception of the images, they showed not to be a Koehler-Escoffier. Some details let me suppose it could be a French or Swiss motorcyle.
The engine is a bit a lookalike a "Fafnir" engine, but I didn't find any reference to prouve.
It likes to be an 500cc with a with an opposite valves steering system.
This is an construction, normally used by older models (around 1900).
Would it be possible to put an image of booth sides of your "1904 James H.Smith's" on this site, because also from your bike I could'nt find any documentation. Thank you.
Untill now I still cannot tell you what brand or model of motorcycle it is, and I'am quiet curious to find it out.
