I finally got tired of looking at the Signet just sitting there on the shelf, and started looking through my old tools for a small right-angle screwdriver. Could have swore I've got one somewhere. No luck there, but I did find an Allen wrench that had been twisted on something that would not budge, so I whacked the twisted part off, then filed down what was left to make a screw blade. Worked like a charm.
Two screws, and the whole top comes of with the rewind crank . Ten minutes later, and the camera was back in operating condition, and I could now see through the viewfinder. I made sure not to try to clean the mirrors, as I've read too many horror stories of ruined surfaces. I just took a soft brush, and some blown air to them, as they looked pretty good anyway. But the viewfinder windows were another matter. What a load of gunk left on the Q-tips! One thing to look out for, you have to make sure that you hold the pawl lever for the film counter to one side with a small screwdriver so it clears the bottom of the counter while putting the top back on.
This is a beautiful camera, and I think it is one of Kodaks better designs, mechanically, and artistically. The only thing it lacks is an accessory shoe.
I'll post the repair photos after the first of the month, when my Flickr account opens back up (I maxed out my uploads this month). Guess I'll have to go 'Pro' to take care of that little problem.
