Pre war K98 bayonet frog unit marked 7./I.R. 77

Excellent pre war most likely pre 1936 production K98 bayonet frog in good used condition. Based on the brass rivets, this is a very early and most likely pre 1936 production piece off equipment. The frog is nicely maker marked but this became rather unreadable, only Berlin can still be clearly seen. The frog is also nicely marked with the unit marking 7./ I.R. 77 which indicates 7e Kompanie Infanterie-Regiment 77. Excellent early frog!
