Could be.  We have tons and tons of 3325Bs and 3325As floating around, 
though. I haven't seen any PTS recently, however, a quick check of the 
asset database shows a fair number of them "owned" by Rabi Wang and 
William Diener. The latter has most of them.. Models PTS040SANIX-7, 
PTS250 and X10SAN10 for the most part.
Both of those guys are in the Frequency and Timing Advanced Instrument 
Development Group.

A couple years ago, we cleaned out some storage closets FULL of those 
gold plated brick shaped modules that made up the Mark III (at least 
that's what I was told).
