It's a Bolex B8 Regular 8mm camera. Kodak stopped making Kodachrome (or any) film for it a few years ago. I believe you can get some European B&W stock...seem to recall a source posted here a while back. I don't know of a source for Regular 8mm color film.

You'd be better off setting that thing on a shelf as a conversation piece/souvenir and buy a Super8mm camera as there is plenty of film available as well as accessories.
