The camera takes 120 film. Lens is probably a Voigtar, which is fine. The little label on the front nearly always falls off on these. Neat little cameras, very small, stopped down they take sharp as heck photos. If the camera is working properly, you shouldn't have to worry about lining up the numbers on the film in the red windows on the back. There is an auto stop feature, and it should automatically stop when you're winding on to the next frame, once you set it at the #1. A manual is nice to get that sorted out, but you can figure it out by playing w/ the camera probably.
