Interesting, mine does not have a HP tag, just a dot-matrix printed label
with one line. Hopefully by next spring I'll be set up to where I can do
some 'real' checking of the the oscillators I have.
Thank you for the enlightenment

When I made the offer for the unit, I took the chance that it might be, I
saw that the s/n was 3505A02095, the same HP prefix
on my other dead dual oven 10811.
When I got it, my luck won this time, one of the coax cables is tagged 10
MHz and the other EFC.

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.

Hate to be an echo but be very careful. What you can get on EBay is things
like rejects, rebranded junk, used pulls. Reports have been published where
even parts that sell for 10 cents were profitable enough to rebrand parts.

I agree with Bob, find a vendor you can trust and make sure you buy from an
authorized distributor or if just need two or three parts try to get them
as samples.directly from the manufacturer. The reason for this is you may
get a fake or reject part and you will never know.
