A beautifully maintained  late-model Myford ML2 with a number of sensible modifications: oiler caps on the spindle bearings; large handles on both top and cross slide with face-locking micrometer dials; improved changewheel studs (not visible); a graduated handle on the leadscrew end and a neat plinth to bring the machine up to a comfortable working height.

Early Myford ML1 or ML2. Note the rectangular-form cast-in leadscrew-support bracket and the gear on the end of the spindle retained by a stop ring. The first Myford lathes were painted black but at some point in the early 1930s the makers switched to what they described as grey/blue but which in fact resembled a horrid "vomit green" .  Very early models had no changewheel or backgear covers and when the latter were fitted the first were rather short in comparison with the later.

The first  ML1 to ML4 changewheel cover hinged on a bar carried on a casting bolted to the back of the headstock.

Note the improved changewheel studs engineered by an enthusiastic (and skilled) owner.
