Manufactured in the 1950s - and embracing the contemporary trend to mount watchmaker's lathes on self-contained, motorised bases - the little Lorch Junior was a thoroughly well-specified and equipped lathe. While the arrangement of bed and headstock might have been a little unusual (the headstock reminds the writer of that on the post-WW2 Rivett) - the rest of the lathe was entirely conventional - though it did include the facility for "Hand graving" - a method first suggested in a sales brochure by Lorch - where a finely-finished and very smooth steel plate in front of the spindle nose provides a surface on which a small toolholder, with a flat base, can be manipulated. In addition, the facility was provided to mount a grinding wheel on the end of the motor spindle so that, with a support table fitted into a hole bored in the casting, tools could be sharpened when held in the toolholder.
Sold complete with a fitted wooden box holding the buyer's choice of accessories, items could include: wire, ring step, step and wax collets, a superb compound slide-rest assembly, two tailstock (one lever action, one with a simple "push" spindle), pump-centre faceplate, precision 3-jaw ring-scroll chuck, carrier chuck, roller filing rest, sinking tools, lantern chucks, Jacot drums, flip-up tool rest with two sizes of T, and a self-centring drilling attachment and plates, etc.
The background to the development of late-type lathes for watchmakers is explained in this extract from the Leinen section of the Archive:
Beginning in the early 1950s, the more expensive versions of Leinen and Boley & Leinen watchmakers' lathes of the traditional WW pattern (a design originating from Webster Whitcombe in America during the late 1800s) were fitted with a much simpler (though more rigid) design of headstock. With the 3-step drive pulley overhung on the left-hand end of the spindle, the Company had adopted the design of the English Pultra concern who had introduced such a type (the very modern-looking 17/50 and 17/70) in 1946 (in a reversal of roles, IME, an English maker of small precision lathes, appears to have taken up aspects of Leinen designs in their second-generation Model 100 and Model 300 lathes introduced in the mid 1950s).
Other changes to Leinen lathes were also afoot and, although some models were to remain unchanged, on some method of mounting the bed and driving the spindle were improved. For many decades a simple round foot, appropriately slotted to take the bed at its headstock end, had been used together with various kinds of effective but untidy remote countershafts and motors. The first improvement came with the use of a variable-speed motor hinged on a heavy, remote base - the second was when the base was extended forwards to form a boss into which the bed mounting stem fitted. The next development saw more complete and integrated designs with the bed sitting in a full-length casting to give an entirely different and much more up-to-date appearance - a typical example being the popular WW82 and WW83 models shown below. Although Leinen had developed their long-established designs, there was no loss of quality - or cutting of corners - and both engineering and cosmetic standards were the same as they had always been: exemplary.  The lathe below is currently for sale
