Austron became part of Datum and Datum ultimately became part of Microchop

I very much doubt a pump outfit actually made OCXO’s

Should be Greenray, which then became part of NDK(?)

A lot of this stuff shows up on various sites on the internet. It’s all a 
bit suspect, just as the often found description of “oscillator non-crystal
controlled” is a bit suspect.

Given the state of the art / OEM market back in the mid 70’s and Greenray 
as a supplier, it’s a pretty good bet the specs are pretty loose compared to 
a “modern” $4 Chinese eBay part …. Some stuff has come a long way in
50 years ...
