And the Print your own labels machines on New Street Station and probably at other places. When I first had a penny to spare in the early 1950s I could emboss a thin strip of zinc with no less than 22 letters, rather like the plastic DYMO machines later, except that the ends of your strip were punched and shaped for fixing. By the time I left Brum, in 1959. I think you could only get 15 letters for your penny.
