I am attempting to get the name, and function, of a machine that I think is a coining press. It's the one in this photo: I believe it was a British-made Taylor & Challen "Knuckle-joint" press. These coining presses were supposedly popular at mints all over the world since these presses employed a knuckle-joint action to efficiently strike coins rapidly while simultaneously inserting blanks and ejecting struck pieces. I believe the machine in this photo is similar to this Hordern, Mason & Edwards knuckle press that is shown in an HM&E ad from the 1960s: I am attempting to gather as much information on these machines as I can for a research piece on South Korea's first coin mint, which went online in 1966. I have some information that the Korean Mint purchased two T&C and two HM&E coining presses to start striking its very first coins that year. From another source, I learned that the Koreans had asked Cincinnati Milling Machines (USA) for technical assistance with installing these machines at their new coin mint. Is this a knuckle-joint press in that first photo?
