3-13/16" Long X 3-13/16" Dia. Projection Lens with 250mm Focal Length
It's a honey of a projection TV lens from parts unknown, but what care you for brands? It weighs 3 lbs, measures a symmetrical 3-13/16" long x 3-13/16" dia with approx 2X-3X magnification and 10"/250mm focal length. We're thinking TV replacement part, DIY telescope lens or the world's heaviest loupe.
