Very early (1953) Myford Super 7 with the integral headstock drip-feed oiler, the circular window of which can be seen just to the left of the chuck - this lubrication system was abandoned after a few year's production.
Another distinguishing feature of early machines was the clutch contained within the countershaft 4-step cast-iron pulley. This works perfectly well, but is prone to rattling unless correctly adjusted. Reference to the maker's instructions on this point is vital.
The levers to operate the tumble reverse and backgear - as well as those to open and close the changewheel and countershaft belt guards - were fitted with screw-operated knobs; the later change to "spring-loading" made the machine rather more convenient to operate but more vulnerable to careless selection of the wrong lever …..
Super 7s of all years are well finished, but these early models appear to have enjoyed especially fine detailing  - and to have been very carefully painted.
