If it's a roundhead student, then there're very limited possibilities.

1) does it have a screwcutting gearbox? 2) if so, is it imperial/metric? 3) on the apron, does the lever to engage sliding or surfacing feed move along under the apron and lift into one of 2 slots?

There were options on screwcutting, but I think most are supplied with the gearbox. There was a Mk 1½ which had the round headstock but Mk2-type apron.

That's about it.

Have a check on

for more info. I did somewhere find on the net a list for translating serial numbers, which IIRC are on the bed somewhere, which let nme know that my Mk 1 is a 1960 model, which makes it damn-nigh 50 years old, and at least 6 years older than me.

yeah, they're all noisy. it's down to the gear design.

Mine's running on a single-phase high-starting torque 2HP motor, but it's a bit underpowered, it could really do with 3HP.

Mine is 1960 and a 1200 rpm.

another difference, IIRC: the Mk 2 has a split (and hence adjustable) crossfeed nut. The Mk 1 doesn't, don't know about the Mk 1½.

Actually, my Mk1 now has a split nut too, but that's 'cos I modified it :-)

Mk 1.5 has solid crossfeed nut. Hood

another item of data for the knowledge-base.

It's not that hard to convert, in fact. I've still got some play in the crossfeed, but nowhere near what it had before.
