The second pic shows them using tongs to pass the iron though the mill.I recall them doing that in Pateg (and in Yorkshire) With heavier sections it was passed through their legs and occasionally so near that their trousers could catch fire. Great to see pics of those days
Milkman - Extremely hard work. Back in 1966, as a student apprentice I worked in Lysaghts Orb Works in Newport, that also had several hand rolling mills. The men worked 20 mins on and 20 mins off, and there was also a "wet" canteen on site that served alcohol, along with large containers of salt. Around that time I also remember watching a program on Industrial Archeology on TV that referenced hand rolling mills and it said that these mills had been discontinued many years earlier, and there they were still in use.
