 Mark: There is a seller on fleaby with the id of Barans Surplus that has a couple of NOS switch assemblies for about $30. Or, you could buy one of the cheap, nasty T-17's and pull the switch out of it and have some other spares in your stock.
BTW, running a search on T-17's was extremely fortuitous for me. I ran across a listing for an Aviometer 9640 Microphone holder, the type I need for my Fairchild restoration project. It's one of those little things that never seem to pop up available in the last few years I've been looking.

 Hello
During my re-enactment event this weekend, I lost AM on the SCR-274N early Sunday afternoon.
I did a quick test on-site and I was getting no PTT from the mic.  The the radio worked fine on CW.
I came home and disassembled the mic and found a cracked part associated with the pushbutton, which I had epoxied some time ago.


When the PTT button is depressed, the relay rotates in the case and the PTT contacts don't quite connect:


Might any of you have the replacement part, or perhaps an empty T-17 case they'd care to sell?
