Is this 1125 OMT kit?

I have 3 engines for my bike. The first is the original 900 engine that came on the bike. The second is an engine from an 83 1100. The third is a Frankenstein made up of some aftermarket cams with a 900 head, 1100 jugs, some pistons that I don't recognize, and a 900 crank and rods on a 900 trans. The cases appear to be 900 but have been machined to accept the 1100 jugs.
Is this possibly the OMT 1125 that is commonly reffered to here on the forum? If so, where do I get one piston with rings to match???? I could put this motor back together with these few parts. I can post some pictures if needed.

I have never taken the head off of my 1125 OMT so I do not know what the pistons look like.

OMT usualy used new 1100 cases (unstamped) rather than machine the 900 cases.

Are the cases stamped?

Don't have a clue on the rings. Let me know if you find a source...

The stamping on the case indicates it's from a 900. Someone went through a lot of trouble to modify this engine and then burned a valve and toasted one piston. Looks like it was running real lean on #2. The exhaust valve was cooked and the rings were seized in the piston. The rest of the cylinders look great.

If I could figure out whos pistons and rings these are I could quite possibly get this motor running again. They're NOT Wiseco for sure. I live down the street from their main facility here in Mentor Oh and took the parts up there to see if they could match something up.....no dice! They couldn't tell me who manufactured this stuff but it definitely wasn't them.
