This item is in like new condition, this was received by me as part of a used camera auction that I received . I have no use for it. Photos I have seen new, show some small plastic insert that is either used to help insert a slide or something.

This appears to work without that piece

Takes either negative film sideways or slides in the top

Threads to 52mm lenses

Also, the magnifier lens that comes with it can be used independently as a macro converter for close focus I learned this trying to figure out what it was

I’m not keeping this and if I was going to keep it , I’m sure the plastic insert that’s missing could be cut out of a scrap piece of plastic or cereal box with a razor blade .

These sell for over $55, get yourself a deal
