Took the initial look at this set. The schematic is a bit problematic. N-202 is not listed in Riders or other sources but after searching around apparently the M102/M111 model is similar and found in Riders.. It has an error which has been corrected by Leigh Bassett and which he has kindly provided.

The set looks relatively unscathed from previous repairs. It will need to be stripped pretty far down since much of the wire is the crumbling insulation of the mid 40's and the tuning cap grommets are all but gone as well. One of the bolts holding the tuning cap down is missing and that has caused it to twist a bit making the dial string bind so a restring will be in order when the tuning cap comes off.
As I looked it over, here's a component I had not seen before:

When I find it on the schematic it looks like its a pair of 60picofarad capacitors, C17A and B on the schematic. A close look and some testing shows the center mounting bracket is ground and there are a set of dielectrics and connection on each side of the bracket. Interesting.
More later...
