[Milsurplus] what xtal set is this?

Tom,

They are for either the BC-659 (SCR-609/610) or BC-1335 (SCR-619).  At the 
time they were repacked, I would guess that they were probably considered as 
being for the latter.  But maybe not.  A lot of crystal sets were made for the 
BC-1335 and so marked.  But they are part for part interchangeable.

The actual operating frequency of the radios, in MC, is the channel number 
divided by 10, so 27.0-38.9 MC is the range.
