Hello.
I recently acquired a box of crystals, which most were marked with their
frequencies. 3 were not, however. but they had a number on them. I have
searched and got nothing at all. Any of you know what these are?

The first is in a tall rectangular package and reads:

XS0041
KDS 5D 3

The second is in a small, cylindrical package (similar to the ones I've seen
in watches) and reads:

XS216B

And the third has the same package as the second and reads:

XS18 62

Thanks much,
   Zach
