[ARC5] Octal Crystals

[mac]

While we're on the subject of crystal sockets/holders....

The Collins 32-RA has 5-pin tube sockets for the crystals and,  
according to the manual, crystals in matching 5-pin holders were  
available from the manufacturer.  Has anyone ever seen these?  I have  
(or have seen) examples of just about every other type of crystal  
holder ever made but not that one.

We have a 32-RA/BC-779 pair at Ft. MacArthur, a configuration that was  
used there during WW2 to communicate with a HQ group located in San  
Bernardino.
