I agree, looks like an OK Cub cylinder.

Re: What Engine does this Cylinder/piston belong to
I don't see a land below the exhaust-port on Eric's cylinder like there is on the Cub. If Eric's has dual ports.. than my guess is wrong.

The engine below is a McCoy .049 "Baby-Mac" which looks to have it's cylinder more like a liner set-into the case.

It's really hard to tell from Eric's photo.. but it appears to me that the port is below the fins.
Eric.. is the piston free in the bore (not seized)?

Re: What Engine does this Cylinder/piston belong to
The OK as you probably know has three small intake holes 120 deg apart that exit in between the exhaust slits (the other two would be out of sight) It is very hard to see but the exhaust groove is there you have to carefully look to the right side just above where the port hole is using the table wood as a background and you can just see it, it appears as a wide gap between the cooling fins and the lower most fin. The piston being at TDC doesn't help with seeing the port. (Bandit)

I fully agree. Confident that it's OK Cub by the look of the round intake port below the land. Piston crown looks right too.

Re: What Engine does this Cylinder/piston belong to
Sorry it was a long day and a short night ,, It does have 3 what appears to be intake holes below three exhaust ports , and yes it is seized or pushed too far to the top of the liner .. Eric
