The Japanese machine I think it’s probably from the late 70s
Well the American machine is probably from 1985, unfortunately with the Japanese machine I’ve had to retrofit a pump onto there as the original one was leaking quite badly, so that’s kind of zip tied through the original bolt holes,
I do have a 1955 Naco machine which is a boltdown , But that one also has a bit of a leak from the weep hole, I’m not exactly sure why or how, but the machine is fully working thankfully, and I have a potentially 1930s or 40s timesaver branded machine, that one has a built-in heater and the temperature control works by setting it to the temperature that’s needed, and pushing in the white button then when it reaches that temperature it releases the white button and starts the motor And it seems like there is also a leak from the door seal a little bit and the drain tap [ for buckets of hot water on the front]
