Thanks John, I think you're right. I've got an old 5x7 B&J back that I'm planning to adapt, but I'll have to build the part that slides into those grooves.
Not only would 5x7 would be easier to find, but having a standard spring back would be nice - the idea of schlepping around both the GG and a separate back as well as film holders sounds like way too much bother.
Thanks,
