Just discovered this over on the Box Camera Revolution discussion forum on flickr:

I'm sure Pablo, for one, will appreciate it!

That brought a wry grin to my face! Especially the section on cleaning the shutter. I found out, by doing it wrong, of course, that there was a reason why the service notes said don't oil the shutter surfaces. I was cleaning up an old box camera (a Box Tengor, but the shutter principle is the same), and put a drop of oil on the shutter blade and plate. Firing it a few times, I could tell it didn't sound right, and looking from the film end, instead of seeing a simple circular blip of light when tripping the shutter, there was a crescent-shaped section which was clearly brighter than the rest of the light coming through the aperture. The shutter plate was bouncing at the end of its journey, and the bounce was enough to bring the shutter blade's opening back in front of the aperture, letting a crescent of extra light in. I quickly flushed the oil out with lighter fuel, then it just got sticky, so I flushed again with a few grains of powdered graphite added. Once the lighter fuel evaporated and I gave it a few more trips, the shutter settled down and worked perfectly.
I've found drawing offices to be a useful source of powdered graphite, and you can get a handy amount in an old plastic 35mm film container which will last forever.
