[Milsurplus] 400 Cycle Meters

[Steve Hilsz]

I found  five each surplus military 400 Cycle panel meters.(I like "Cycle" 
better than "Hertz" when referring to vintage surplus).

Two have 3.5 inch bezels with 2.5 inch glass and read center-scale 400 
Cycles with the low end at 395 Cycles, high end at 404 Cycles. Manufacturer 
Varo, Model 6500.

One more is of the same manufacture but is Model 6500-1, this is the style 
with phosphorescent scale.

Two are reed-type, Triplett Model 33-FP-9M, mounted into a 3 X 6 inch 
vertical panel, the meters measuring 2 3/8 inch across the glass, and 
mounted at the upper part of the rectangle. The low scale is 380 Cycles, 
upper scale 420 Cycles.

These appear to be used but were apparently tested, as some have military 
shop tags attached. At any rate, if they don't perform correctly I won't 
"stick" you with them.
