I have a HP / Symmetricom unit that has a dual oven 10811 that was part of a telecom master clock distribution system that was only meant to run in a controlled environment.
I'm not 100% positive, but I believe the OCXO in your photos is not an HP 10811, but rather the Symmetricom version, which uses a 5MHz crystal and a frequency doubler. I bought a 58503 that the seller guaranteed had a 10811, but it turned out to have the Symmetricom oscillator instead. When I pointed this out, the seller offered to refund me the price of a DO 10811, which I accepted. Just for curiosity's sake, I ran the 58503 as it was, and after a time it settled into being one of my most stable OCXOs -- better than all of my 10811s.
