[Milsurplus] Disk voltage regulator

[Miguel Bravo]

I have got some mil type sealed envelopes containing one "Disk voltage
regulator" each. It is a very fragile disk with the following data:

ELECTRICAL RESISTANCE: ANY ACCEPTABLE
DIAMETER 2.625 INCHES NOMINAL
THICKNESS 0.031 INCHES NOMINAL
SPECIAL FEATURES SOLID
MATERIAL CARBON

The envelope has the following marks:
H6110-643-4936
140951
DISK VOLTAGE REGULATOR
1 EACH
N104-83998
A-3000132-15-4/62

What equipment it is for?.
