[Milsurplus] CU-737/URC antenna tuner manual?

[Nick England]

Howdy gang -
Does anyone have a manual for the CU-737/URC (Collins 180U-2) antenna
tuner that I could get a copy of or borrow to scan?
This is the manual tuner used with some AN/URC-32 transceivers.

The military manual is NAVSHIPS 93628(A) but I assume there was also a
Collins 180U-2 commercial manual.
I've got a schematic from the AN/URC-32 transceiver manual, but I'm
curious to see what the tuner manual says about operation.

Many thanks,
