Data Needed: Jackson 420, Jackson CRO-3

[Fred Olsen]

Greetings all,

Please forgive the off-topic post, but I'm getting a little desperate
and need wider coverage.

I'm looking for manual/schematic/alignment-calibration for a Jackson
model 420 "Universal Oscillator" (signal generator, 100kHz - 34MHz), and
a Jackson model CRO-3 oscilloscope.
(Jackson Electrical Instrument Co., Dayton, OH)

Reasonable price or copy charges gladly paid.

Thanks, Fred
