I got two used from China, they are six years old that is the standard
time when the whole board get replaced in a cell phone base station they
looking like the drawing in the data sheet except pin # 6 is missing but
it is not connected anyway they have EFC pin and it is working I tried
it with multi turn pot and the unit's own reference, the two kept the
relative phase on the scope in ±10° for two days relative to each other.
Does your unit has the pin -- which is not connected inside -- or the
whole pin is missing?
I f you want to open the can get some very thin beryllium-cooper foil
and push it into the slot after you heated up the solder, that way you
could separate the bottom plate and the can without doing major damage.

may I get some copy of that datasheet?
I don't have the correct datasheet. The seller has a catalog page, but
it doesn't have specs for the non-EFC unit he's selling:

I have not tried opening the case to determine if the EFC could be
restored/hacked back in.
