Need Help identifying a Cylinder/Piston
I have a Cylinder/Piston combo and I don't know who made it. Here is what I do know. It threads onto a cox crankcase without issue. It will seat a Pre-1955 Cox Glow Head, however the fins of the glow head hang over the fins of the cylinder. If I use a shim on the bottom of the cylinder, it will make a complete rotation without any issues. The cylinder fins are thick and symmetrical. A picture is attached. My first guess was that it might be from a cipolla but I haven't gotten a good picture of the .049 I have only seen the .061 version, and they don't look the same. Any ideas? Thanks, Andy

Andy: is the piston similar to the cox piston ball and socket arrangement? do you have a separate picture of the piston? It sort of looks like the piston has a pin thru the piston like larger engines as seen (?) thru the exhaust port on the cylinder.
here is a picture of the standard cox piston. (thanks to cox international)
edited 8p.m. found a picture of a cipolla 1.5cc if this helps.

Re: Need Help identifying a Cylinder/Piston
I do not have a picture of the piston, but I will try to get one up by the weekend. The piston looks pretty much like a standard Cox piston with the exception that it is somewhat rounded at the top. Inside where the connecting rod attaches to the piston, it looks like an old style (3 piece) cox piston. Andy
