Keystone 8MM Vintage Projector PLEASE READ order

Product Name: Keystone 8MM Vintage Projector PLEASE READ order
It's in wonderful condition and it does work. I did not have any knowledge of using this projector, though I did try taking old family film through it and using it. After playing around with the features, It did have a burning smell. The cord is excellent and not damaged, but the bulb is original. Not sure if there is any factors there. It just may be I was playing around with the knobs too much order not knowing what I was doing, so I turned it off. Just a warning to someone wiser than myself.
