From an as yet unknown maker, the "SL2a" lathe was manufactured during the 1950s in the former Democratic Republic of East Germany when it was occupied by Soviet communist forces. Advertised in a leaflet put out by a central distribution organisation, the Deutsche Handelszentrale Machinen und-Fahrzeugbau, it was listed alongside the quite different MDO250/400 lathe made by Gustav Eisfeld of Gera (in the Thüringen area).
With a 100 mm (4") centre height, the SL2a was available as either a short bed model admitting 500 mm (19.7") between centres or as a long bed that took 850 mm (33.5"). The bed, in the English style of a flat top with vertical, narrow-guide edges (just like a Myford Series 7 lathe), carried an oil-bath, geared headstock with 3-speeds in which ran a roller-bearing supported, 14 mm bore, No. 2 Morse spindle. Drive came from a 2-speed 0.25/0.5 h.p. motor (though how this was mounted is not known) to give a total of 6 spindle speeds. Screwcutting was through a tumble-reverse mechanism and changewheels - of which a generous set of twenty-four was provided to cover both inch pitches from 8 to 40 t.p.i and metric from 0.35 to 2.5 mm. Collets were amongst the accessories, a set of 23 being listed from 1 to 12 mm in steps of 0.5 mm.
Although no photographs of the lathe were included in the brochure - only an artist's impression - the fact that the compound slide rest appeared to have been bereft of micrometer dials might not (one hopes) have applied to production machines.
The SL2a required a space 1200 mm long, 500 mm front to back and 400 mm high and weighed 115 kg complete with all its equipment.
