I have updated, partly, the section on large subminiature format cameras at
http://www.submin.com/large
The manuals for the Compass, F21 and Ensign Midget are now available.
For the Compass the original and the Compass II manuals are posted along
with a book Photography Systematised and Simplified and a film price list.
Some of the documents are in a very fragile state.
Under http://www.submin.com/large/collection I have included some
photographs of the Compass tripod and roll back.
