[time-nuts] Oscillator help

[Glenn Little]

I have a board marked DMEC M1 Supply that contains a Toyocom TCO-929A 
oscillator.
This probably came from some type of small aircraft navigation equipment.
The oscillator has a date code of 8922.
It has 4 pins and a trimming capacitor on the side.
The frequency is 10MHz.
 From the part number I would guess that it is temperature controlled.
A search shows nothing for this part number.

Does anyone have any further information on his oscillator as to 
stability, accuracy or similar?

Thanks
Glenn
