[ARC5] Crystal tester.

[Rich Post]

The military used this one (TS-39B/ TSM-1) and likely some other crystal
testers

You can also simply plug a crystal into a grid dip meter in place of a coil
and check the freq on a counter.

A third method is shown in the third picture down, using a sig generator,
scope and counter.
