[Antennas] schematic needed for Collins 180L3 ant tuner

[rb]

Thanks to Larry (KQ4BY), I think the schematic I'm looking for is part of
the Collins 180L3 antenna tuner.  I found pictures of the inside and outside
of the 180L3, and there's a good chance the motorized vacuum variable module
I'm looking for a schematic on is part of the 180L3.

I checked the BAMA site, and the 180L3 isn't listed there.

So, where am I likely to find this circuit diagram?
