the Bendix RA-10 was capable of being crystal controlled and used three 
pronged crystal sockets.  These look like they might fit the RA-10.  I 
have a RA-10 receiver that had provision for two xtl controlled 
frequencies between 2 and 10 MHz.  I think the crystal was 1630 kc below 
the desired operating frequency.
