This is a vintage Bentley Super 8 home movie film projector monitor, model BX-11. It is designed for projecting Super 8 movie films and is likely to be of interest to collectors of vintage movie equipment. This thing works off c batteries. At the time of the listing I didn't have any c batteries available so I'm selling it untested but I think the power is just for the light bulb and possibly to move the film from frame to frame unless it's a manual operation. I'm not sure selling it as shown as listed as is. All sales are final, no returns. Lots of other vintage electronics along with military surplus. New and used car parts. New tools finish toys items, industrial hardware, gold and silver coins. Us stands trading cards 2,350 plus items listed this week most on sale. Please take the time to look at some of my other listings and as always any reasonable offer would be considered and combined shipping on multi items when possible.
