[nordland77]

Hi,

I found stempel of Feldpostnummer 34578. From http://photo-war.com/eng/ it is:

(Mobilmachung-1.1.1940) Panzer-Abwehr-Sturm SS-Leibstandarte Adolf Hitler,
(28.4.1940-19.9.1940) Panzerjäger-Sturm SS-Leibstandarte Adolf Hitler,
dann Panzerjäger-Sturm verstärkte Leibstandarte SS A.H.,
(1.10.1940-27.2.1941) gestrichen,
(1.3.1942-7.9.1942) 2. Kompanie Pionier-Bataillon 371,
(12.3.1943-7.9.1943) gestrichen (Stalingrad),
(23.4.1944-24.11.1944) 3.8.1944 Stab II u. Einheit Artillerie-Regiment 1544.

I would like to know at what point in WWII could be made this stamp. It is possible that I have stempel of Leibstandarte?

Thx for help
