Oh that's nice. Like the colour. Just want to add that ive been looking for some sort of uniform structure for lorch lathe models for about 6 years. Usually they have letters and numbers, the letters being the centre height, then the type of lathe, then the numbers being the spindle bore. Mine is an A11 for example, which is a 100mm height.

Lathe Instruction Manual

Lorch made a wide range of high-quality watchmakers' lathes in both Geneva and WW pattern branding them Lorch, Lorch Schmidt and L.S. & Co. However, like most other manufacturers in the field, they were also content to market models under other names with corners cut in material quality and cosmetic finish - one of the most popular lower-cost models being the Geneva-pattern Triumph.
Lathes were available with 6 or 8 mm collets either individually or in boxed sets, these being listed from No. 1 to No. 12 (and possibly higher); however, as boxes were offered separately for owners to mount their own collection of accessories, it is not always possible to categorise them exactly.
A typical set would have been the No. 2, an outfit that provided the typical watch repairer with all the basic equipment he needed. Sets 3 and upwards included such luxuries as a compound slide rest, two types of tailstock (with a sliding spindle and a lever-feed spindle), drive plate, screwcutting attachment and changewheels, vertical milling slide, pivot polisher, milling and grinding spindle, 3-jaw self-centring chuck (sometimes called a 'Universal Chuck'), 4-jaw independent chuck, drill chuck for headstock or tailstock use, wheel-cutting attachment with division plate (to cut what the laymen would call gears but which are known to the watchmaker as 'wheels'), a 'Mandrel' - in effect a spare headstock with a 'faceplate' attached used for super-precision work, a headstock that could be swung with an overhung drive pulley - and numerous smaller accessories including a single or double roller rest, fixed steady, saw table, Jacot Drum. pivoting attachment, lapping attachment, wax chucks, button or crown chucks, wood screw chuck, wood turning chuck, emery wheel chucks, lantern chucks in bronze and steel, circular saw chuck, carrier chuck, balance chuck, micrometer-adjustable boring head, adjustable eye glass and a self-centring drilling attachment, etc..
