[ARC5] German WWII keys

[Bill Fuqua]

   I have 3 German WWII keys that share one interesting trait.
Two are the same, each has precision micrometer dial adjustment for contact 
gap and a key click filter built into the base.
The third, an new addition, is a simpler one but still enclosed as the 
other two.
All three have two sets of contacts, one normally closed and a silver 
normally open contact.
But the most interesting thing is they all make a sound while using them 
that sounds just like an old
Morse Sounder.  It eliminates the need of a side tone when sending CW. I 
have always had a problem
sending with a straight key without a side tone but have no problem with 
these.
