I just bought what I thought to be a Bolex Rex-5 off of eBay. I received it today and the body reads "Bolex H16 M." Now I've done my research and I'm pretty sure it isn't a H16 M. First off, it has the three lens turret. And secondly, it accepts 400' magazines. It doesn't have a turret lock though which I believed to be a feature of the Rex-5. Also, there was no viewfinder mounted on the top of the camera. It came with an Octometer but shouldn't there be a viewfinder on the top? Any help is appreciated.
