Hi Jim, Interesting WB you got there. Just to make things more confusing, are you Sure on the 7? Is it possible that it is a 3 (old style)? Maybe it is a 93, they have some different pin setups. My 93?s have the new style of 3 (round).. And ball hinge. I have not seen that kind of hinge you got on you?re Badge before on type 2 1939 WB, only on EKI 1939, Interesting. I have two different makers ending on a 7, (black wb) 107 and 67 And I have L57 (no /) in my files. I will do some more research and see what I can find. Any chance for more detail pictures front and back. Best Regards, Ronny
