Built in Germany by Leinen, the Paulson was a lightly modified Model WW80 built for distribution by Henry Paulson & Co. of 131 South Wabash Avenue, Chicago 3, U.S.A. The exact specification is not certain, but Paulson are known to have required a "micro-feed" tailstock spindle with a micrometer dial engraved with metric divisions (and for the spindle to take collets); an improved tailstock-to-bed clamping arrangement; dust-proof headstock spindle oil reservoirs and a headstock pulley with three rings of indexing holes: 50, 56 and 90.
Of standard WW specification, with a 50 mm centre height, the flat-topped, bevelled-edged bed could be had as a single pedestal mount - in which case it was 280 mm (11") long  - or as a 400 mm (18") long-bed version with two feet. The usual central T-slot was provided to secure headstock, slide rest, tailstock and other accessories. The headstock spindle, to take 8 mm collets, used a traditional watchmakers' lathe assembly of double-cone bearings in hardened and lapped steel with lubrication by simple but capped oilers. At least two versions of the screw-feed tailstock were produced: an early version with a conventional full-length screw and small micrometer dial and a later one where the spindle could be pushed freely though the screw-feed unit and then locked to it in the required position - this type having a much larger, easier-to-read engraved ring. As an option the lathe could be supplied with a tailstock having a simple "runner" (push spindle) assembly.
A wide range of accessories was offered, all drawn from the standard Leinen range, that included a multi-speed countershaft, lever-action collet closer, lever-action tailstock, a saw table, dividing head, compound screw-feed slide rest, vertical milling slide, high-speed milling and grinding attachments, a mandrel faceplate and the usual selection of collets, cutters, wax chucks, arbors, centres, etc. Beautifully finished in nickel plate with chemical blacking of small fastenings, the lathe was manufactured to a very high standard and today is comparatively rare..
