[time-nuts] 10.23 MHz SC cut 10811 compatible crystals available

[Richard (Rick) Karlquist]

Someone was asking about SC cut crystals to play with.
I have a few dozen 10.23 MHz SC cut crystals that are
interchangeable with 10811 10 MHz crystals, except for
the frequency difference.  They were made for a GPS
version of the 10811 that never saw the light of day.
Any interest in these?
