A friend of mine has bought a just out of calibration R  & S XSRM Rubidium 
standard from one of the so called "recyclers" on  Ebay.
Although the price was good, and it came with the off air  receiver, phase 
meter, and frequency divider, it looks to have been heavily  decommissioned 
with deliberate damage to the internal wiring and the  rubidium lamp removed.
We've found the relevant manuals online and he's confident he can  repair 
the wiring but he still needs to locate a lamp.
If anyone has a working lamp available, or might know where one  could be 
obtained, please contact me off list.
He did comment that the lamp assembly looked as though it might accept the  
lamp from an Efratom FRK, can anyone confirm this?
Alternatively, is there likely to be any risk of damage to the  FRK lamp or 
to the XSRM lamp driver if he tries it but it's not  compatible?
