I've got several Superior brand instruments, all VERY old. Did you restore it? If not, I'd be very careful using a 45+ year old instrument without restoring it.
FWIW, I use a restored EICO 147A for signal tracing, very easy to use and quite common. The manual is in the public domain, easily obtained. 147's and 147A's show up on fleabay often - just get the demodulator probe!
I've got a 1940 Superior Test Oscillator - and a copy of the schematic from either a Riders or Beitman manual. I found the copy at the ODU library here.
Cheers,
