I was reading a book today (yep, made from real dead trees) on camera history and got to wondering if there were any MF cameras designed and made (possibly with masks) to cover all the major MF sizes - 6x4.5, 6x6, 6x7 and 6x9. I wouldn't expect such a beast to stray much further into the panoramic class - 6x12 or higher, but that would be interesting.

I know several folders have masks to cover both 6x4.5 and 6x6 or similar arrangements. But aside from fabricating masks for my own 6x9 Ikonta folder, was there ever a model designed specifically to cover all four sizes?
