More pictures might help. Looks like it might be an early motorcycle engine. Any carb or ignition parts with it?

Looks close, or possibly just like a 1911 Vintage Excelsior Auto-Cycle built by Excelsior Supply Co. Randolph Street Bridge, Chicago, Ill

Could be off of a different brand, but definatly a motor cycle engine.

If im not mistaken that appears to be an early harley davidson single cylinder cycle engine. Possibly250-500cc
But I could be wrong. Its hard to tell without actually seeing
it on person. I would check with vintage Harley Collectors first
to get a positive ID on that engine.That would Be your best start . Good luck to you

Whatever brand this is hasn't been mentioned yet. I do not know what it is but I don't think it is as early as the design suggests. The end of the crankshaft is speaking to me, I just can't hear what it's saying. It has flat spots milled off with a hole through the milled area, not threaded on the end to hold a pulley or sprocket. Looking forward to seeing some pics of the other side.

I'm no expert by any means but I am convinced this is not a Harley as they had a external rocker arm and they had their name embossed on the bottom of the crankcase and a serial number at the top of the crankcase where the cylinder met and there was also a number on the base of the cylinder too. Also with Harley's they had a magneto this one appears to have a battery and coil system since I don't see a bracket for one.

Could be a lesser known maker, most older big names had their names embossed on it somehow.

FWIW, H-D singles didn't get the mechanical intake until 1914, and the magneto was an extra cost option, not standard equipment.

Reviving this older post. Have the same unidentified engine that I recently found. I'm hoping someone can identify. Already determined that it isn't a HD. Hopefully this will help maak also.
Any help appreciated.
