Infrequently encountered, even in its German homeland, the Dolze & Slotta lathe was manufactured in Coswig, Saxiona. The company described themselves as "Spezialfabrik für Drehbänke in nur zwei  Größen" - in other words, a specialised manufacturer who made lathes in two sizes only.  Matra, another German machine-tool Company also branded this lathe as their own, an example, complete with the original German screwcutting and speed charts, having been discovered in the United States.
Of conventional design and construction the first example shown below, a Model DSPN, used a flat and V-way bed, a geared headstock with neatly group speed-change levers, a multi-plate forward-and-reverse clutch built around the laysahft, a Norton-type screwcutting and feeds gearbox and a carriage assembly that could have come from any lathe from the 1930s onwards.
If any reader has a Dolze and Slotta machine tool, the writer would be pleased to hear from you.
