[ARC5] VHF AN/ARC-5 more small details

[Mike Morrow]

The contract numbers on the AN/ARC-5 VHF components that I've seen all have
Army-type order numbers of 7461-WF-43 on them.  I have a two-transmitter
rack MT-71/ARC-5 with that same order number on a black and silver paint
phenolic screw-held name plate just like those on almost all the VHF
components made by Western Electric.  Yet it has "CBY" on the plate, so it
must be A.R.C. made.  It surprised me to find an AN/ARC-5 rack that didn't
have a familiar rivet-held metal with blue paint name plate, and that A.R.C.
made components on the 7461-WF-43 order number.

Isn't it odd for a set which seems to have been predominantly a USN-utilized
set to have an Army-type order number on it, even in light of the VHF
components being a direct descendent of Western Electric's VHF SCR-274-N?
For that matter, what about all those R-1/ARR-1 receivers that have
Army-type order numbers on them, but also USN anchor ink stamps on the
paint?
