Standard 8mm cameras (pre super8) used a special roll of 16mm stock. You shoot, the camera capturing/exposing down one side of the roll, until the spool is done, , then you flip it over (no shit) and expose the other side of the roll - then when you developed it, they split the roll and splice it. Super8 came along and was way more user friendly - just a frigging cartridge you plopped in. I was getting Super8 developed at Walmart as late as 2001 or so for like... $5/roll, but I think those days are over. That Revere is a really good looking little number. I wouldn't necessarily waste money shooting through it - it's an expensive way to record ~6 minutes of life. EDIT: shit... now you've got me going... I love vintage home cinema stuff. Here's the camera I keep at my desk. It's not actually a nice camera per se, and I've never run anything through it - but I liked the way it looked and it was at a thrift store for nothing. I don't think I'll ever shoot through it - it's simply a little reminder to forget about my day job and go make movies. ALSO - http://camera-wiki.org/wiki/Revere I love this stuff.
it's a pretty standard, japanese knockoff 8mm camera. It's a little special (but not at all unique) because it has a three lens setup. You just swivel the mount to choose which focal length you wanted (tele, wide, standard). Pretty standard on older film cameras (before zoom was a thing).
