Ancient, "Heavy Duty 1/2" B&D Drill Info?

Hi Peter,
These drills were a great machine, and date from the early 50's, you cannot buy parts for these now, although many other old B&D machine use the same / similar parts.
To 'test' the switch, it is easy to bypass it, as it is just a standard switch, to do this, first put the drill into a vice (to stop it from moving around if / when running), then take the 2 wires out of the switch from the motor, join 1 of them to the live input, and the other to the neutral wire, remembering to attach the earth wire to the body, then switch on at the plug, if it works, then the switch is at fault, if not, it is most likely to be the brushes, these are a round brush, unique to the B&D range, these are long since obsolete, but I still have a few sets of old stock should you need any. It may be just a sticking brush, if this is the case, simply remove the brushes, clean them, making sure the brush holder is clean, and the brushes slide freely.
Hope this helps.
