I saw the show on TV and recorded it to try and get details of who made the instruments. I recognised south wales but no futher. Any ideas who the guy is and how he trades?
Howard, looks like Caerbont based in Ystradgynlais in the Swansea Valley. Smiths had a factory there (nicknamed the Tick-Tock factory) and several years ago it closed. It was resurrected by ex employees as Caerbont Automotive.
