M6 was in the 2. Minensuchflottille together with M2, M9, M10, M11, M12, M13 from oct. 1939.
Name: M6,
Construction: Oderwerke Stettin, 1937
Launched: 08.01.1938
Commissioned: 06.06.1939
Fate: Sunk after mine hit near Lorient on 23.10.1941.

I guess some cannons could be used somewhere in Norway, but I dont know if they did or where exactly.
