H-hey,
Thats a very rare triplet lens designed to properly project curved screen crt tvs, and there is a good chance that it will have bad edge focus on a flat source such as an LCD. I have a lens similar to it, and when tested with an LCD, it didnt focus perfectly, but can still be used (sure as hell will beat a singlet lens!) Its very sought after in the DIY CRT projection world. It also was sold as a Polivision-4, along with a high gain silver screen (13.2 gain!). Diameter is over 150mm! The focal lenght is not too long, around like 300mm?

Thanks ancorp. I was hoping its focal was a bit longer.
