Through the kindness of Mike Morrow, KK5F,
I've acquired a two transmitter MT-71 AN/ARC-5 rack
that has been reworked from an SCR-274N transmitter rack
under Army contract number 7461-WF-43.
The rework was done by none other than
Aircraft Radio Corp.

Evidence includes:

1.  Repositioning of the centered transmitter number plates
to the side, making room for installing the "test" switches.

2.  Drilling of the round channel for the "test" wires
through the bottom supports; the de-burring marks through
the original paint are deep and conclusive.

3.  New CBY nomenclature plate with the AN/ARC-5 nomen
and the Army contract number.

The rear box has been replaced entirely with an
AN/ARC-5 unit, which is probably why A.R.C.
got the bid to do at least some of the rework:
they were already producing these boxes;
Western Electric would have had to tool-up for them.

Thanks again, Mike for yet another "piece of the puzzle."
