[MRCA] WW2 Boom Mike Element

[Michael Hanz]

Are you talking about the M-6/UR microphone element, Mark?  If so, be 
aware that there were later aircraft boom mikes that have identical 
snap-in carbon elements that are more stable.  The ones I have used in 
my H-46/UR headsets are labeled M-51/UR and CW-292/U. It appears they 
aren't expensive - 
https://www.ebay.com/itm/M-51-UR-CARBON-MICROPHONE-ELEMENT-FOR-MILITARY-RADIO-NEW-Mfg-Audiosears-/263323881053 
is just one of many sources.
