I used to rebuild these units many years ago and they were quite a good oscillator - these units would be good for a few parts in 10-9 and 10-8.

Yes, it is. For a picture look here:

Should you be unable to download the manuals, I could send you at least the schematic diagram and component location of the Freq. Std.
I have one of these oscillators, and years ago I used  18VDC for testing. It is rated at 10E-8 per day, and has 5MHz, 1MHz and 10 MHz  plus 2x500KHz outputs. As you may have seen, it was used on a radio.
