Thanks for the compliments!!

That set has a military surplus CRT; I think it's an HR21GVRP22. HR-something anyway. It isn't any brighter than the regular ones, but it was easier to get convergence and purity. I think they still use those in some airport control tower radar scopes. They're still on the current US Navy inventory sheet, according to one of our members here who is an active Navy tech.

The contrast is probably better because I put the original tinted glass from the Zenith 21FBP22 over the existing bonded glass on the tube. That photo is taken while I had it on for the '07 Rose Parade on New Years.
