From these pics, it appears to be a late war 214 original mount...although in poor shape. Note the "0" marking on the left, unknown what that means, but appears on late war mounts for some reason. Maybe somebody else knows more details?
So there would be mounts numbered with only this 0 and other examples would be known.
Does Brian have a photo of a "0" mount?
Waffenox you did well to ask the question on this forum!
Makes me think I have an early mount '214' edit to show you
I do not have a photo, sorry.
I have seen several over the years though. Not really sure what the meaning of the "0" means. Some say post war French use
proof and others say late war German proof of some type. We may never really know for sure.
