[MRCA] Trivia Question

[scottjohnson1 at cox.net]

Just a guess, but maybe a common interplane freq.? (126.18 MHz), or maybe on HF using the fundamental.  If for VHF, it would follow there be an equally common receiver mixer crystal.

I have a bunch of them around, and 7010 is quite common here as well.

With your kind indulgence,  I ask the following: 

Why do we find a proliferation of surplus CR-1-A crystals cut for 7010 kHz?
