Feldpost numbers

[Lehr Grenadier]

Needing some help with Feldpost numbers, I have a small collection of original postcards

44711 Or its 447ii card dated 21.7.1941

14916 dated 06.10.1941

36291/C dated 14.08.1943

Last one doesn't have a number as such but the stamp on the card reads 3 (M.G.) E. 486 from what I can make out

Cheers,

[Chris Pittman]
