[Milsurplus] Collins Modulator module

[Michael Kane]

Looking for someone who may be able to identify a module I found in a
trailer load of assorted electronics droppings from a deceased estate sale.
Measures 90mm height,120mm width and 80mm depth. Uses 2x 6159 (24v 6146)
recessed in chassis and 1x 5814(12AU7) , 1x 5726 (6AL5) , 1x5751 (12AX7).
Previous owner has written Collins AM HF Transmitter on cover. The module
has a
plug on bottom with 12 small and 3 large pins, marked P1401. Two pots on
bottom, R1404 clipping and R1403 gain. Module mounts onto I assume main
chassis, and secured with two screws with heads painted red. The mod
transformer is not included, and is external to this module.
If someone can identify I would like to use this in my next homebrew AM
transmitter .( Don't ask why) Schematic would be great.
Thanks...Michael VK4ZKT
