Very nice video!! This describes the operation very well. Thank you.

This camera does not need film in it to fire the shutter.

 

The shutter "flap" is operated when the spring goes past its cam point and kicks the assembly around the hairspring. The outer gear/cam has detents that change where/when the flap gets bounced back to closed. I suspect it is common for some one to have turned the small flat head screw on the outside too far and disengaged the brass plate that holds this "kick" spring. IF this has happened, when you shake the beast, it should have a rattle in the front shuttter box. This small screw is there to adjust the shutter speed so if you do move it you should set the shutter speed with it when your done.

Yours looks like it is missing a screw, that must set shutter speed. and a brass thing that causes the shutter to snap shut when on T mode.( thats the part that took me a long time to figure out. Any how this is a picture of a fully funcitoning THE 800 shutter assembly .

I took mine apart to see what made it work and to see how hard it would be to modify for 4x5 work. I lost a spring (found it) then spent a couple of hours putting it back together. here are some pictures.
