Kriegsmarine Marinesonderdienst and Kriegsmarine Far East operations Feldpost numbers

[Hans Mcilveen]

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.
