[Milsurplus] Crystal information

[Bob Camp]

Hi

The crystal holders are all based on US military specifications. The 
relevant military document was MIL-C-3098. It has morphed into 
MIL-PRF-3098. There are more than a hundred slash sheets associated 
with the specification. Each slash sheet describes a specific crystal 
and it's holder. Some of the slash sheets for the early crystals have 
been out of print for a while ....

The original crystal holders pre-date the current military 
specification system. Most of them stayed around long enough to be 
included in the newer documentation setup.

Hope that helps.
