To the right of this assorted collet set is what looks like the proper ManSon collet-mounted spindle adapter to carry chucks and faceplates (the other collets are Moseley or G. Boley copies of the Moseley "conoidal" type with a trumpet shaped and longer than standard WW types that the DuoLathe accepted).

DuoLathe rheostat motor speed-controller foot unit. This controlled a "universal motor" able to be used on 105-120 volts AC or direct current that gave a range of infinitely variable speeds from 300 to 3000 r.p.m.
