Correct, this old Folding 6x9 camera's shutter stopped working so I removed
the bellows and supporting structure and glued a flat panel onto the body.
The pinhole is about 35mm from the film, unfortunately I get some vignetting
from the primitive shutter so I need to crop a bit to get a rectangular
image.  Also the pinhole is a little large (~0.3mm) so I really should
make/buy a smaller one to get a sharper image.
