I think they are recycled from phone or cell phone upgrades.

Symmetricom has gobbled up most of the alternative sources.
The data sheet is readily available.

Probably. Do you have any way to sanity check it?
The spec sheet says aging is <1E-9 over 10 years and it's within 5E-11 at
shipment.
The C-field adjustment covers +/- 1.5E-9.
(Specs are from a 2003 sheet. Older units are probably a bit less good.)
