Pete,
Those are apparently BFO crystals X3 and X4. There is no current or
past mod to replace the BFO crystals, so you must have ordered them as
replacements. If you do not have a problem with the BFO range, I
suggest that you simply keep the crystals, but if your BFO range is not
correct, try the new crystals to see if it is resolved.
