Hello, can anybody help me assign these Feldpost (sub)numbers to named units? M 06204 P 4 M 06204 P 6 M 06204 P 18 M 06204 P 30 M 06204 P 34 (see image) M 06204 P 36 I have been able to positively identify M 06204 P 37 as belonging to the tanker 'Brake'. The entry for 06204 in Kannapins Feldpost?bersicht states: 06204 (25.1.1943-31.7.1943) Kriegsmarine-Dienststelle Bordeaux, Schiffsverband, 06204 (24.3.1944-6.11.1944) 17.10.1944 Sonderdienst Marine- Ostasien. The meaning of the letter P is unclear. Probably not Penang, 06204 numbers seem to have been assigned to units in Japan as well. Hans
