There's a history to many of the GPSDO products you hear us talk about.

I believe the original TBolt (fancy red case) did have an OCXO but it wasn't particularly high quality. Perhaps Bob can shed light on this.

99% of TBolt's found on the surplus market today, and all the ones in the TAPR deal, have a surprisingly good OCXO's. These were customer specials as best we can determine, and never described on Trimble's web page. They are in the plain brushed golden color aluminum case.

The Thunderbolt E is a relatively new product (fancy blue case, ROHS-compliant) and isn't yet on the surplus market.
