Luftwaffe Ground Combat Badge

Late war badge made of zinc with all grey finish, does not have the silver eagle at top but has the hole for the rivet, does not look like it ever did, have seen others like this. Backside is all grey and unmarked, the pin hinge and catch still have the silver plated finish, they are all nonmagnetic. Overall badge shows very little wartime wear, just the finish went away with time. Exc. + $250.00
