Norman my handsome, That is a stainless steel companionway from a milk processing plant at Davidstow airfield. I bought three short and one long. £500 the lot with stanchions and 2" rail piping for each, the long one I'm intending to place at the far gable end of the bungalow as an emergency exit as the attic has a nine-person sleeping capacity with access on a very tight spiral staircase at the near gable end, Bought them four years ago but now, no longer have the strength so must wait till I get more kids around.
Most people downsize when older. Wrong thing to do as the kids go but keep returning with spouses and then grand-kids so one has to house them ALL and when you live in a fantastic location as I do they keep returning.
