    I've been working on a set for my 8x10, and the concept is fairly straight forward, but getting an original set is quite the nice find. I *think* that you can get the geared tracks for to make a replacement rear rail from Microtools, but I've not measured the teeth myself so they may not have the same measurements as the originals. The woodwork is a snap, but I've always had a special place for original parts...

I do about 15-20 minutes in the morning and the evening, and it's slowly coming together. From the outside it looks pretty good, and I've got no leaks at this point, so from here on in, it's just a matter of finishing up the regluing and putting an extra coat or two of the patching compound so that it doesn't come apart in the field.
    With the rear track and stablizers you have a great 7X17 camera.

    It really is worth a new bellows. If you don't want to go that far, I would suggest taping the corners with 3" wide book binders tape (see Gaylords). Just extent the bellow all the way out and lay the tape flat on the four corners, then carefully fold. This will give you almost a new bellows since virtually all of the pinholes are on the corners.

    Actually on mine the corners were good, unlike what one would normally expect. The leaks were mainly from just the delamination of the wooden stays that form the folds from the outer covering, and then the large center strips on the outer covering were coming apart from the strips running along the corners, and the fabric inside was cracking at all the folds.

    Eventually, I'll probably just get a new bellows, like I did for my 11x14", but the patching is going well enough that I'll finish it and see how long it lasts.

    David-

    I own a Hyperion soft focus lens made by the Seebold Invisible Camera Company. Of course they HAD been made by Gundlach so this all fits together. Thanks for the research.

I've found a few references to the history of the company, all acknowledging the oddness of the name, but does anyone have any idea why they meant by "Invisible Camera Corp." I'd hardly think of using a 7x17" camera if I wanted to be "invisible." Or was it the corporation that wanted to be invisible?
    Just guessing but Kodak introduced 16mm in 1923, so it might have been that they adapted the gauge to surveillance use, as you suggest later in the thread.

    I have also owned several 35m remote triggered surveillance cameras, but don't remember the manufacturer; they had a motion picture-style pull down claw and provision for a 50 foot load BUT pulled a 8 perf horizontal image rather than the standard 4 perf high motion picture frame....

    Yes, I wanted to make my own Vistavision camera, but like most overly ambitions projects...

    Here are some pictures of the camera from the person who sold it to me. I didn't buy the lens, since I already have a 10" WF Ektar--

    Definitely a nice looking 7X17 Korona. And that camera is still a real user.

    The case configuration appears to be something that a lot of Koronas, both 7X17 and 12X20, had. I have one of those cases that originally came with a 12X20 Korona, same configuration, i.e. space for the camera and three of four film holders. I sold the Korona and now just use it to carry extra holders.
