My mom got me a slide projector for Christmas. It was the slide projector that she used at the jewelry store where she works. It has the name "JC Penny 500" on the handle. IT uses a Kodak slide tray. the lens says "KEYTAR LENS" on the top and "COATED 4IN f:3.5 ANASTIGMAT" on the bottom. Does anyone know who made this projector? Could it be a low end rebranded kodak projector?
