Hi, my old maintenance job was with a large industrial company that had various sites throughout Britain. and some in other countries, and they also had British Standard recognition, myself and a workmate had to go to one of their sites once a little south of London, to take out a small plant, for bringing back and reinstalling it inside a new building on our own site, and in their workshop was a Myford lathe, I can’t remember which model it was though, but it was bench mounted. Now although they didn’t have heavy plant at that site, it was still an industrial one, so yes some big industrial industries did use Myford lathes.
Regards Nick.
