Cast aluminum crew signs for the ship like this seems to be pretty hard to find …. Probably because the other signs were much easier to locate and a little more “glamorous”. This is a cast molded piece .. of course out of lightweight Aluminum. This particular crew cabin would have been certified as being large enough for 21 seamen to occupy (who would have slept in Aluminum standee type bunks). Can you image all those seamen crammed into one room? Pretty rare to find these!
