Some parts arrived today and I made some progress on reassembly. There were 3 parts in the rebuild that were completely missing from this transformer: the tube insulation (ZW-81) on each side, a bushing (ZW-157) on each handle spindle and a spacer (ZW-166) between the contact plate and contact springs on each side. Maybe they made them without those parts back in the late 40's and they are part of the reissue of the 275 watt ZW.
We're getting closer!!!
