[Milsurplus] Unk Relay

[Hue Miller]

I found this mil looking relay, overall is about 5 x 2.5 inches.
Huge coil at one end, 2 x 1.5 ins., marked "24V". At the 
'inside end' of the coil, a plunger is pulled into the coil,
actives a lever which has a 2PDT throw with a 1/2" 
contact travel. There is a mounting bar marked 'S7'
and also marking on coil frame, "Peter Bros. Co.
TYPE 45-A".  I would only want to keep this if it's for
the ATB, ATD, or BC-307, but I'd bet money it's more
like for a TBW or TDE or something like that. In which
case, it's available free.

I also found a meter, 2 ins. round face with 4 mounting
flanges at the corners like Bendix direction finder 
indicators. However the scale is all-black, no numbers
or figures at all, only a center tick market and it and
needle look radium painted. Came in a box with 
instructions on how to use with variable resistors to 
build an antenna rotation indicator, which I'm quite
sure are aftermarket.
