Sb

I think someone converted a pin back to a SB. It is a Deumer schinkle. Jim

It is an original screwback, not converted.

[Eklipse]

It is with an early nut of the button type, and sunburst or clamshell disc (may be the screw has been resoldered. Schinkel frame. Nice very early piece.

I reason I said converted is the rust mark at the top and bottom, like something had been removed. But I leave it to the experts as I have only seen the clamshell attached the other way and the pin back. Jim

IMO the back attachment is original, early one. Later, Deumer changed it to a simpler type.

I see an original Deumer Schinkel SB here. I don't see anything strange in this cross. The base for the screw ia aomething what I usually see on 1920/30's pieces from Deumer.
And the parts on the reverse that have finnish removed, they are just worn
