We are headed out for the evening so this will be very brief and I will try and followup tomorrow. While I don't disagree with some generalizations as early no tie Luftwaffe frogs tend to follow the pattern. It's not an absolute: Posted is a Luftwaffe unit marked long thread, and no (zero) center thread. And if we go to an earlier image # A and #B are either natural or bare leather not coated brown or black. I also have the E.O.G�tze large washer Luftwaffe marked frog in black which has (from memory) something else different which I will have to look at later. Best Regards, FP
