[Premium-Rx] Looking for a reference standard for my Racal RA3700 series RX

[Ron Ott]

The 10MHz (or is it 1MHz?) reference oscillator has died in my Racal RA 3711 and I would like to replace it with a "new" one, if possible.  If you have one to sell, I'd love to buy it.  I understand there are at least two variants of this osciallator used by Racal and I assume that either one will work.
 
If anyone has more info about the part numbers for the proper assembly, please send them along.  I presume the 3700 series used the same ref oscillators.
 
Thanks, Ron/W6XY
