I was looking at some pictures of lathes in the catalogues of certain well-known traders. My wife understands this need and only objects mildly to the time I spend with 'dirty Gerty', my Myford, in the privacy of our garage.
Anyway, a couple of the mid-sized machines have a leadscrew reverse on a knob at the front of the lathe. This does not look like a tumble reverse. Rather, I guess there is some kind of selector fork behind the panel. The Chester DB10 is an example:
