The Mikro-Mir kit is supposed to be HMS M.1 - but as I already had a resin model of M.1, I decided to make HMS M.2 - before she was comverted into an aircraft-carrying sub. The only changes I made were to source the M2 decals from my spares box - white characters on top of black to get the 'shadow' effect. I also left off the deck gun - Internet photos show it not fitted.... The M-Class were nicknamed 'Mutton Boats' - because the 12in gun mounting looked like a leg of mutton. HMS M1 and M2 together...... This is another in the expanding range of 1/350 scale subs from Mikro-Mir I understand that they are planning to make HMS M2 with a hangar and floatplane - plus M3 when she was converted into a minelayer.
