PLESSEY PR-2250 Spare parts.
 

I'm from Italy and I'm searching for some PR-2250 spare parts, in
particular:
- A Symmetrical 1.4 MHz filter with 3.0 KHz bandwidth (just like the
one employed in the "Module 3" - not 3D -).
- A complete "Module 7" (with the oven-controlled Reference
Oscillator).
Any idea about the availability of the above parts?
Thank you!!!

Best 73,

Paolo
