driver

Hello all, new to the forum and general machining. I need some help identifying my late grandfathers lathe. It doesn’t have a lot of the manufacture’s stamp on it anymore. All I can gather is a watch company’s name (image below). That’s the only identifying mark I can find. The lathe still runs...

Thank you for any info in advance guys. I am buidling a 12 z I H mill to cnc .I would like to use j3 or j4 mitsubishi servos and drivers. Im on a budget and am finding j3 and j4 servos but no sets together.So the question is can you use a j3 servo with a j4 driver or vice versa.
