See http://www.lathes.co.uk/depoy/ for background information on the company and the two basic model makers lathes made by this company. This particular machine was owned by a engineer who used it for his model making hobbies. He made live steam scale locomotives.

an excerpt from Tony's site:

"...The other Depoy, which may have been a later model or offered simultaneously with the cheaper version, was of surprisingly heavy build with a wide, flat-topped bed (with feet at each end) a shallow gap and angled sides to guide the carriage. With a swing of 4.5 inches (2.125 inches over the tool slide) and a capacity between centres of approximately 9.5 inches, the lathe was around 24-inches long, 6-inches deep and stood 8-inches high. Robust, with a well-braced front wall, the headstock had a ¾-inch diameter, 3/8-inch bore spindle (with a No. 1 Morse taper socket in its ¾" x 16 t.p.i. nose) that ran direct in the cast iron with the 1-inch long bearings closed down by screws set to the rear. Although not fitted with backgear (for slow speeds) the lathe did have screwcutting - or at least a power sliding feed - with a shaft taking the drive from the changewheels to the tailstock end of the bed where, using a pair of 11t and 33t reduction gears, the drive was stepped forwards to rotate the 7/16" x 12 t.p.i. (Whitworth-form) leadscrew. As a (long) full nut was fitted under the saddle, to allow the drive to be disconnected a simple push-pull button was arranged at the tailstock end that allowed the 11t gear to be disengaged - the leadscrew could then be turned by hand using a rather elegant "balanced" handwheel.
It is believed that the original gear train consisted of a 22t spindle gear meshed to a 60t gear attached to the under-bed drive shaft (the idler gear being 44t). Combined with the 11t and 33t reduction gearing at the tailstock end this would have created a (rather fast) 108 t.p.i. rate of carriage feed.
Unfortunately, only a single swivelling tool-slide was fitted, driven by a 5/16" x 16 t.p.i. feed-screw and mounted in a most unusual manner - a large, centrally-disposed V-way on top of the saddle that allowed it to be easily and quickly positioned as required. Although simple, the slide was another hefty unit, with its handwheel being large and easily gripped.
One significant design flaw concerned the tailstock: with the front of the casting set vertically to the bed - instead of being inclined forwards - the 1.75-inch travel of the 5/8-inch diameter, No. 1 Morse taper spindle was such that it would have been impossible for very short pieces of work to be supported between centres.
A number of accessories were offered including a ring-scroll 3-jaw chuck, 4-jaw chuck, catchplate, milling slide with integral vice and, most surprisingly, a miniature capstan attachment.
So far only one of the cantilever bed models and two of the twin-foot type have been discovered. If you have a Depoy lathe, or any further information about the company, the writer would be interested to hear from you.."
