[Milsurplus] Stray meter found

[Hubert Miller]

So i thought before I gave the meter i would take a look at my Navy ME radio, which I hadn't looked at for years until recently 
closing a rental storage. The meter is identical to the receiver section meter of the ME radio.  So I have a spare; not that it's 
essential at the rate I have used the radio so far. But looking at the ME, i think it would be real fun to operate.

SE-3060 Type ME
Westinghouse Co. 
Observation Airplane Radio
3000-4000 kHz 50 Watt
Date Jan 1929 Serial 6 

Uses 4x WE 215 tubes; none populated in the radio. I will probably think about some tube adapter for submini triodes?
Transmitter has 2 tubes. Don't know what PA tube as it broke in shipping, years back.  Has 3 crystal channels. Crystals are
unique in that they're in "flat pack" about 3 x 2 x 1/4 inch which is held and contacted by spring metal clips. 

>Betcha that first meter was from the Navy RG receiver, that used CW-1344 tubes.  Local notes on the CW-1344 say:
 
CW-1344        (WE) 215A; Navy spec.RE 13A 219.  Three in RG rcvr., 1925.  Note:  nominal fil. voltage for these is 1.0 V, but for a time tubes were graded and tip-coated with red lacquer (for 0.85-0.9 V), none (for 0.9-1.0, or blue (for 1.0-1.1).  The fil. voltmeter in the RG had red and blue bands on its scale corresponding to these voltages.
 
This is from, in part, examining an RG at a Military Radio Collectors Group meet in Southern California.

>>I found a small voltmeter, white face, around 2.5 inches  ( it's not at hand at moment ), two scales;
one FS looks like 60 volt, the other 2 volt; with a center of 1 volt and legend, something like "Adjust
filament voltage for correct tube bulb color". I think 1920s Army. Any idea ?
