[time-nuts] Austron 1120-2 Oscillator

[Ed Palmer]

I just picked up an Austron 1120-2 oscillator.  I've looked around for 
info on it and found the datasheet on Didier's site, but not much else.  
There's a sticker on the side that reads:

  -A1-
248096
5MHZ STD

A stamp on the unit reads:  PT NO.248096
I also found that it has an NSN number of 5955-01-020-4487

It came with the mounting bracket and socket so I know that it was 
removed from a piece of equipment.

Does anyone know what equipment used this oscillator?

Thanks,

Ed
