[Milsurplus] WWII Crystal Confusion

[WA5CAB at cs.com]

Mac,

No, the FT-241 holder is only slightly larger than FT-243.  Same pin diameter 
& spacing (0.093" and 0.50"), about the same height and thickness and about 
30% wider.  Different construction method.  The FT-241 holder was also used for 
a 200 KC reference crystal in the ATC and AN/ART-13, the BC-652 and probably 
others.  FT-241 became DC-2(*)/U.
