I may find one at http://www.russiantubes.com. If not, I can suffer with
a 3" crt.

I'd have to look on the tag. I actually did find another display shortly
after I obtained the first one. My hope is to fine a new CRT just to
avoid all the potting compound on the plug end of the CRT. That and
getting hook up data on the original CRT would be next to impossible.

Yep. The jet had a flameout on take off and since it was too heavy to
horse into the air safely on one engine, the pilot punched out. The jet
hit the ground at 300Kts+ and the cockpit section broke free of the main
fuselage which burned. This happened in 1996. I managed to get the HUD,
MPCD, TEWS and VSD plus other sundry parts out of the wreck. It was the
ultimate find for my project for sure. Every one of those boxes are made
of 100% pure Unobtainum. (they also happent to be filled with glass
shards. :) )
