At one time I had an old (c.1946) Myford lathe and I remember it had an adjustable auto-disengage for the leadscrew. Looking at photos of more recent models, this feature seems to be absent. Can anyone clarify, is the feature available?

I cannot comment on the Myford 7 series, but I wondered if you meant the "M" type when I read your first post. There are a lot of "M" types still around doing good work, and some people prefer it to the 7 series. They frequently come up on eBay at pretty good prices, though in a whole spectrum of conditions, as you might expect...
If you search Yahoo Groups for "drummondlathe" you will find a fairly active group of 600 or so members.
If you're interested, look for one with a reasonable set of changewheels. The number one question on the group seems to be: where can I get changewheels? With regard to other spares, it's a lathe, so you make your own.
