Unknown German Piston...thoughts?
 

Can anyone recognize this piston? It is still in the sleeve, but should be easy to ID with the arm.

I have ruled out DB601, DB603, DB605, BMW801, Jumo211...

Any thoughts?

Thanks!

Mike

Yes, 211 from the secondary rod side. Bore (piston) dia would help!

Well, it is either 211 or 213 with the liner studs. Not much more to go on without some numbers. Get the liner cut off and the piston will give lots of info. Also, the style of big-end bolt trap might give it away with more detail pics. HTH
