Hello Andy and a belated welcome from me. Nice to see a paddler in "uniform"!. At present I am building Talisman in her wartime guise HMS ARISTOCRAT, but at present only slowly progressing. I was lucky enough to contact two of her crew who served on her for the whole of the war who could fill me in on lots of little details of fittings , service etc.
Jeannie Deans was only a minesweeper for a very short time as in 1940 she was converted into an"EAGLE" anti aircraft ship when she was totally rearmed. The guns you can see in your wartime photo are 2 pounder pom poms fore and aft. I cant find my eagle boats file but I think her armament was as follows: Four 2 ponder pom poms, three Boulton and Paul four -gun turrets (ex Defiant turret fighters), one either side of the after funnel and one on a pedestal mount aft of the funnel. She also carried several 20mm oerlikons. and several twin rifle calibre machine guns (Lewis). For a short while she also carried an unrotated rocket projectile mount. The bridge was heightened with an open bridge above the wheelhouse. The depth charges werent so much for hunting submarines as she was blind (no asdic) but they were used for exploding acoustic and pressure mines. I wiil search my files out and give you a full rundown ASAP. Regards, waltere.
