Does anyone have any experience with the Datum/Efratom LPRO-101
Rubidium standard? There are large amounts of these on e-bay.

The datasheet specifies life time to "at least" 10 years
and the one that I found on a flea market is dated 1999.

I assume that they are replaced as a planned maintenance
and the unit that I found was said to be in good health.
