So I'm going through my father's old plane equipment (he doesnt build kits anymore). I find a teasure trove of engines, mostly OS Max and Super Tigres... and this big boy.

He doesnt remember what it is, it had to be purchased in the late 90s. I assume it's a clone and I don't recognize the logo. All we can remember is that it was going to be mounted in his bi-plane to give it a more scale look.

It's a big sucker, it's got a 12 stamped on one side and the M logo on the other. See the picture below.
Can anyone Identify the make and model of this sucker?
I appreciate the help
