[Elecraft] Old Tyme Mics for the Elecraft K3/K2?

[Ron D'Eau Claire]

Having once again taken the venerable old D-104 to bits (and I hope that
fellow enjoys his D-104 - apart from all else it is a "classic"), has anyone
else gone further back? 

 

Perhaps using an F1 button (the "poor Hams" mike of the 1950's, liberated
from a telephone handset)? It was a carbon button microphone with quite good
audio characteristics for voice.

 

Or perhaps 1930's broadcast microphones like the Olson/RCA velocity ribbon
mics. 

 

After all, my favorite key is a Speed-X bug, a key developed by Les Logan in
the 1930's although mine is from 1952 and my straight key is a WWII J-38. 

 

Surely some dedicated phone operators interested in history have mics going
back that far...
