Not a watchmaker's lathe in the normal sense, but what might be described as an unusually large set of what are known as "Turns". The bronze headstock of the 6-inch long machine is stamped "WW" for "Wilderness Works" - which does not refer to the more usual Webster Whitcombe - but the premises of Robert Pringle & Sons, Manufacturing Jewellers and Goldsmiths located at 40-42 and 3836 Clerkenwell Road, London, in what was then the heart of the English watch and clock-making trade.
Robert Pringle & Sons was a highly successful company and specialists in the manufacture and both wholesale and retail sales of exquisite jewellery and tableware. As such, they would almost certainly not have made lathes, 'Turns' or their accessories - but more than likely bought these in from E.Millen, a maker of precision bench lathes based close by at 68-70 Clerkenwell Road. If not E.Millen, then there were several other possible London-based sources of such items including J.Munro,  J.Buck, Gray & Sons (established 1822), C.H.Joyce, W.Hayward, Hunters Ltd, W.Cook, W.Gale and Pfeil - or even from one of many local jobbing machine shops then present in the area.
Like the other English lathes for watchmakers with bronze castings, the Bolein and CLH, the "Pringle" also had just a simple T-rest for graving work. Of the simplest possible design and construction, the headstock and tailstock appear to have been identical with the former able, after slackening a round, knurled-edged knob, to be slid along the bed--this being a round bar with, cut along the length of the underside, a V-shaped groove. The carriage was just a bored casting that held a T-rest, mounted on a pair of round bars and so able to be both raised, lowered and adjusted inwards and outwards.
Power might have come from a foot pedal or a hand-turned bench countershaft, the drive being by a thin "gut" belt to a 2-step "runner" fitted with a long drive pin to engage, for example, a "dog" clamped around the job to be turned.
When new the lathe would have been supplied with some form of foot, probably round with a stem slotted to accept the tenon on the underside of the headstock.
Sold as boxed kit, surviving with the lathe shown below are six runners, though a set ten or more would probably have been supplied originally.
