[SixClub] Crystal Question

[KA2AEV at aol.com]

Okay heres one that maybe someone will know the answer to or maybe direct  
me in the right direction for an answer
 
Many years ago in a Galaxy far away (Oh wait  )
 
Anyway Radio Shack used to produce scanners with crystals
Does anyone remember what type of holder those crystals were
(The small ones not the FT407s or FT470's that we used in 
our radios before VFOs (Man am I dating myself or what?))
 
Any ideas?
