I need a photograph of a 1939-40 brake lever and throttle lever.
Or original supplier name.
I have one brake lever, but have never found a close match. So I am not sure what was on the bike. The lever that I have seems a bit beefier than bicycle levers.
Any help greatly appreciated.

Reference 1939 ServiGlide:
Turned over the engine with a drill and it had spark. I had been told not to expect any spark because of its age. Next, I installed a lawnmower carburetor of unknown origin. I then turned the engine over with a drill and it quit running after the primer gas was used up. Positive thing is that the engine fired up and got a few revolutions. Gary Wollard had told me several years back that I should obtain a Carter Model N carburetor, which I had done. I then installed the Carter carburetor, gave it a shot of primer gas and cranked it over with a drill. The engine fired and ran like a charm.
