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.
