[Milsurplus] [MMRCG] Navy RAS Receiver - Better Audio Fidelity?

[Nick England]

Project Zebra and ERUPT - shipyard refurbishing gear after the war. Shop 67
IIRC.
See July 1948 BuShips Electron
https://www.navy-radio.com/manuals/electron.htm

I believe all gear introduced after the war switched to gray from black.

Navy gear from 1945-1951? was a darker shade of gray. I use Rustoleum Dark
MachineGray for older gear and Rustoleum LightMachine Gray for newer gear.
They are both gloss rather than semi-gloss, but I am not picky.
Light Machine Gray is a very close match to the official 26307 and Dark
Machine Gray looks like 26152 which seems to be the older color
==================
According to MIL-E-16400 governing Navy electronics equipment:
The paint spec for Navy electronics equipment for Interior Use is
MIL-E-15090
http://www.wbdg.org/ccb/FEDMIL/dtl15090d.pdf
The paint is called Navy Formula No. 111
The color must match color number 26307 of FED-STD-595
Semi-gloss DTM alkyd enamel.

See FED-STD-595C 26307
