Picture 1, post 1, the "19" and "40" appear out of alignment (from the pic) which is not a good sign for something that was supposed to be made in a UKicon factory. I would have expected these numbers to be evenly spaced and in line with each other if the number was punched in a UK factory. This is because the normal way of stamping/punching a line of letters or numbers, in a factory, is to hold them in a tool holder which keeps the punches in-line. These ones look hand punched, i.e. out of alignment.
