Classic Front Projection Tvs

[TV Engineer]

I just acquired, free from it's original owner, a Mitsubishi VS507R front projection TV. It was made in 1982, and is the fold-out-mirror style that was popular at the time. It's in as nearly flawless condition as I've ever seen a used TV, and the previous owner even gave me the owner's manual and remote with it. It has 2 A/V inputs and a stereo amp, so it's pretty "modern" by most of our standards! LOL.

Anyhow, after a lense cleaning and some touchup on the convergence, it's got about the best picture I've ever seen on a 50" projection set. So much so that it replaced the 30" digital set that was in the livingroom.

Since then, I've acquired an RCA PGR100 and a Sears (Sanyo) 50" of the same type from postings on Craig's List. Both were easy to get running, and both show very nice pictures. Unfortunately, the screes are damaged on the RCA and the Sears.

Does anyone know of a source for the "silvering" that was used on these curved screens? Or a source for a new screen? (Does Sears have parts for old sets in their warehouses somewhere?) Or the gain of the screen, so I can try to find an acceptable substitute? Or anything about the screens used with these sets? Or a parts source for them? Also, I'd like to find a manuals for these sets.

Please help guys. I know the collective knowledge base here will have the answers I seek. Thanks!
