From a local branch of the R.S.A ... have been there as long as I can recall, My mates and I would play on these as kid's, 40 odd years ago, 2 Oerlikon's and a Bofor, was surprised to see a wooden "bearing"(?) on the Bofor, cant recall seeing it before, I guess it would be Lignum Vitae? , an old friend who was a 3rd engineer told me once his first job as an apprentice in Durham was to clean the Lathe's after turning that wood for ship's bearing's/sleeve's
