Big size soft shell holster designed for US/UK revolvers.
Markings : on top of anterior flap, the maker’s name = ROBERT LARSEN in BERLIN SW68 which is SIMILAR as the logo used during (and before WW2 !). The serial number is also present (5552) and another unknown caged marking (PPBln).
So be aware that the German’s maker name even if authentic could lead to an error for the period of assembly !
This holster is detailed in the book about WW2 German Military HOLSTERS on page 72.
