Thanks.
I can now see that the small spindle is in fact a brake on the headstock. Also, the speeds are shown on a plate inside the back cover.
I had been concentrating on the cleaning process before exploring the mysteries of the beast - and thought I'd get the info from a manual.
Thanks again.
Watch out - newbie about!
Well, not quite - but been idle too many years!
I have been given (yes given!) a lathe as above. It is in a very rusty state - but motor and bearings etc are all Ok and seems hardly used. I have tried all over the 'net for a manual. Draper / Google / EBay / Ask etc - no...
