Ensign Box Form Camera Shutter
This old camera had a shutter that kept jamming. I wondered why as these old rotary shutters aren't exactly complicated. Turns out a piece of wood had come unglued and was getting stuck in the shutter.
Interestingly, the whole shutter is attached to the inside front of the camera (I would call it the front standard, but it isn't really, as the lens is attached deeper inside the cameras as one can clearly see).
