Looks like at some point an E. Jopp advertised as having a firm previously known as Emil Kerner & Sohn(Waffen von E. Jopp, vormals Emil Kerner und Sohn).

The following is a double by Ernst Kerner with January 1950 proof. I've seen some interesting standing breech stamps, but this one takes the cake. Anyone think it is a turkey over FB? I think it was meant to be an Auerhahn or grouse?




Kind Regards,
