Hi, I'd like to add my two-cents worth to this topic. As best as I can remember, I never saw a Royal Marine with a beret or cap that had a hat band with anything except a R.M. badge. R.N. ratings wearing the traditional sailor's uniform, cap without peak, bell-bottom trousers and jumper with a 'blue sailor's collar with three white stripes', all had a cap with a ribbon around it with only 'H.M.S.' embroidered on it. Whether the ribbon with 'H.M. Destroyers' or 'H.M. Submarines' was officially approved, I cannot say. As someone has said before, it was for security reasons that the ship's name cap tallies were dropped during the Second WW for sure. Cap tallies with ship's names, and the names of shore establishments, such as H.M.S. Victory, etc were reintroduced in 1945. I served in the Fleet Air Arm in the later part of the war. When I was drafted from a Naval Air Station in Scotland, (H.M.S. Fulmar), back to my home depot of Lee-on-Solent (H.M.S. Daedalus) for demob, I and the other members of the same draft were stopped by a Gunner's Mate for not having cap tallies with our ship's name. He was most upset when we explained that none were available to us at our old Air Station In fact most of us had to wear our Number 1 uniforms as we had been unable to buy replacement Number 2 uniforms. Now this may seem strange that we had to buy our uniforms, but at that time, all ratings were given a uniform allowance, and after the initial two free uniforms received on joining up, we were allowed to purchase from civilian tailors or from 'slops', the navy's supplies. Coming back to the Royal Marines, as I remember, they mostly wore army style khaki 'battle-dress', with a shoulder flash saying 'Royal Marines'. Dave in Quebec.
