Thanks. That's a good link and the site has a lot of useful information on it. After a little research, I discovered there's a US War Department publication from 1944 called TM 11-2352 (Camera Equipment PH-104). $20 and a few days later, my nice hardcover copy arrived from Abebooks.com. In addition to some useful information on how to destroy your camera to keep it from falling into enemy hands, there's a huge section on maintenance with detailed exploded views of every part of the camera, shutter mechanism included. Now I just need to find a trashed Anny to use for parts.
