das ist eine finnische Feldpostnummer. wenn jemand Literatur über die finnischen Feldpostnummern hat...
Hallo,
keine Literatur, aber Finnische Kontakte ;-)
Der schrieb Folgendes dazu:
"Fieldpostnumber 3631 belonged originally to Sisäv.LE = Inner waters fleet staff. In some point of war it has changed to 3.MeriK/Laat.RPr = 3rd sea company/Lake Ladoga coastal Brigade and after that to E/MeriP 3 = Staff/Sea battalion 3.
5.Kpk is this units 5th fieldpost office. I can´t say right now where these units have been located during the war, but this number connects them to Finnish army navy anyway."
