Steinar, The hoster is not the right one with the gun, but it is a 1939 with the usual nazi eagle stamp with svatzika nest in the claws.
I can only see part of the manufacturer stamp, looks like: "????RLBUSSE MAINZ", and the colour is dark brown.
Edward: I had no nazy eagle large enough to capture on the pics with the Luger so the turkeys had to do it.
Well I�´m out to the range with the Luger. About time..... It has not been fired for at least twenty years.
