I am looking at an EK Co Ball Bearing shutter that probably had a Rapid Rectilinear lens at one point (aperture is labeled 4-128). It has a pneumatic shutter tube but also has a ratchet wheel with a window, positions numbered 1-12.
Any idea what that is/was?

Sounds like you have a shutter from an early 4X5 or 5X7 Kodak Premo camera. The ratchet wheel was used when you used a Premo Film Pack in the camera. There were 12 negatives in the film pack, and you could keep track of how may were exposed by turning the wheel every time you took a picture.

Well, I never thought of that...
