Leather strap with 17 holes and 54 cm (21⅓ inches) long including the buckle. Made from vegetable tanned leather. Buckle is aluminum original from German stocks. Very high quality.
We have straps with stamps: Anton Kreisel 1939 Ludenscheid (for Wehrmacht and SS) and SS/RZM (for SS only).
It's the earliest variation of the strap. Later during the war straps with steel parts appeared and a model without tongue. Such straps were made also after the war.
