Details:
I'd be very grateful if you could help with identifying a lathe I've just acquired - I've attached a few photos.
I've looked everywhere, but I can't find any markings on any of the castings. I've also tried every search I can think of on 'lathes.co.uk'!
It appears to be British (everything's imperial) dating from the 1930's or '40's
Centre height is 31/4" and about 15" between centres.
Bed is 'flat-top', 33/4" wide, with the shears 7/16 thick and with a central 'slot' 15/16 wide.
Headstock is attached by four bolts and spigots into the bed 'slot' (with two 'push' screws at the rear to push the tongue to the front). Nose thread is 11/8" x 9 tpi and is socketed 2MT.
Tailstock is very like an ML7 - 1" diameter x 2MT barrel, with the handwheel retained by an 'arc' of metal set into a slot in the tailstock casting and engaging with a groove in the handwheel spigot.
What is the unusual feature, however, is that the main leadscrew is 3/4" diameter x 10 tpi, with the half-nuts in a vertical dovetail slide on the back of the apron and cast in iron.
Changewheels are 16 DP with a 5/8" bore and a keyway.
It's missing a topslide (when I got it, it was fitted with an ML7 slide, held in place by M6 bolts into tapped holes in the top of the cross-slide - very 1930's British!
Any clues you can give would be much appreciated.
