Pigeon postmaster

[2ND. PIONEER]

Hello all
Not sure if this is the right forum if not let me know
Does anybody have information on German ww2 Pigeon postmaster
Brieftaubenmeister?
I was able to find pictures and a little information on the web but nothing real specific
Was this service active the whole length of the war?
Was it renamed / desolved and if when?
Was the Gothic B trade patch worn untill 1945?
Any information would be much appreciated

thanks

There was a pigeon carrier troop based in Norway throughout the war and in the Norwegian national archives i found several wehrpasse to men from the unit.
