Looking for FTS1000B OCXO schematics or scrap unit to buy for reverse engineering

Hi,
in my effort to understand the FTS 1050A in detail, I am somehow stuck
at the part of the 1000B OCXO that is in the dewar (see attachment).
Mine will not come apart without using force, which I want to avoid with
a decent working unit.
Other than the unlikely case that someone has the schematics of that
part, I would be interested to buy a FTS1000B without missing parts that
is not working (to keep the costs reasonable, from Europe would be
ideal) for reverse engineer the schematic. The part of it in the
attachment would be enough.
I will share the results here.

Yves there was a time-nuts post in 2009 on the 1000b and the link to at
least some good pictures and details are still good.
Stanely created the information. http://www.n4iqt.com/fts1000b/pictures/
Good luck.
