[Boatanchors] Mystery Clark headset plug question

[Walt - WB2VSJ]

It's a U174/U type.  Fond it on the David Clark page for your headset.

Subject: [Boatanchors] Mystery Clark headset plug question

I have a David Clark H7041 headset that has a special plug. It looks like a
short 1/4 plug but it is actually .280 in diameter and 3/4 inch long. It has
4 contacts (2 for the mic & 2 for the phones). A guy in my local pilots shop
said it is used in helicopters but I got the headset from a shop that works
on fire trucks. I think it was used on either their radio or intercom (or
both). The pilot shop had an adapter that converted it to a pair of standard
1/4 stereo plugs for $56! A picture of the plug is here:

Anyone know where I can get a socket for this plug?
