I’ve been trolling though the Hath-trust website, trying to find details in the
shutter in Metrogon Aerial Camera K17-C lens cone. One blade is either loose,
or missing, so I was looking for details or a diagram before I go in to fix it.
I ran across a little gem of a government publication. It includes
instructions, and a list of tools to use, if you need to destroy your darkroom.
Enjoy:

The Hathi trust is where a lot of the copyright free material scanned by the
Google Books project ends up.
