Feldpost Einschreiben 1942 ???

    Hello, I bought this Feldpost Einschreiben 1942.

    My question:

    1. this Feldpostamt 09541/B,

    What does "B" mean?

    On Feldpostamt's web page, I didn't find 09541/B.

    2, what does this "Stab III U. 9.-12." mean?

    3, this infantry regiment in Russia, at 1942?

    Thank

    (15.7.1942-24.1.1943) Stab III und 9.-12. Kompanie

    Infanterie-Regiment 330. An "A" or nothing stands for the Stab, in this case it is meaning "Stab III. Batallion".

    The "B" stands for the first Kompanie of this Batallion, in this case for the "9. Kompanie"!

    Best Regards
