I'll send you a pic of the motor in bits.
Cant quite figure out the variable speed and reverse part of it as the lever only seems to let one brush touch the commutator at a time and theres no sign of a rheostat.
The motor itself was probably an educational toy. It would probably have been used on meccano or something like that.
The tuning knob is a one piece affair so theres no fine tune. The scale on the knob is 0 to 180 degrees. Still haven't replaced the detector yet but until I do I'll use a Ge diode.
I'll also send you a pic of the gauges and rectifier from my 1954 Dale generator that I'm restoring.
