[Milsurplus] MRC-92A power supply

I have, what may be, a prototype MRC-92A.
This power supply snaps onto a PRC-150 or similar radio allowing it to 
be powered from AC or DC.
Does anyone have information on this supply?
I would like to get the pin outs of the power input connector.
As this may be a prototype, and is probably non repairable due to the 
way the modules are potted, I will probably scrap it and use the case to 
build a power supply into.
I would like to keep the original connectors and make it compatible with 
the original.
The MRC-82A connectors are probably the same.
This was made by McDowell Research which was acquired by Ultralife.
Any help appreciated.
