[Milsurplus] Any PPI display guys out there?

[CL in NC]

I have a brand new in the original shipping box, 16" diameter CRT that went in the radar PPI display of the FAA ASR 8 radar system.  The display of course could interface with different radars, but initial installation came with the ASR 8. The paperwork with it was from Video Products Inc., of Garden Grove CA with a 1982 date of test where the tube was evaluated for operation.   I don't know if VPI built them, refurbed them or just tested them.  The company is gone, a business called Trystar in the building on Lampton Ave. now.  I did email them to ask if Trystar evolved from VPI since they are in the electronics biz.  Anyway, if somebody knows somebody that needs a new tube, let me know.
