[time-nuts] 10811 serial numbers

[Daun Yeagley]

I think the numbering scheme was changed a few years ago.  The 2850 tells us it
was built in 1988 (28 years after 1960).  I think this portion has been dropped,
perhaps when the spin-off from HP happened. I lost track of that in my last few
years there.  The A (in both cases) signifies that it was made in USA, and the
last part is the actual serial number.

   How are the 10811 OCXOs serially numbered ?
   I ask this, because from a photo on eBay I saw a 10811-60111 with
   serial number 2850A47273, a rather long number. The 10811-60111 in my
   5328 counter has as S/N the number A03912, which looks like it belongs
   to a different numbering scheme. Anybody knows ? TNX.
