I have not one but two of these gems sitting in my office right now... 2 channel crystal controlled repeaters in a nice battleship grey cabinet. I believe BLM used these here in the western states for quite a long while before switching to Daniels.
A factory test sheet in one of the 3 service manuals I have specifies .15 uV sensitivity at 12 dB quieting; .21 UV sensitivity at 20 dB quieting with a whopping 8 ma draw in standby, swinging to 1.8 amps in repeat. Overall looking at the design, it appears quite logically laid out. Looks like power output is around 8 watts and factory spec was 145 to 174 MHz in 1983. We're looking at rerocking it for 147 MHz as a portable repeater in a Pelican case with a Q2220 duplexer... ICM has already quoted $21 a rock with a 2 week lead time. Any one have a chance to work on one of these before?
