Jody - it looks like a 5x7 with a 5x7 back from an 8x10 "adapted" (guessing at the film size, but something like that) ... yeah, not the prettiest solution. If nothing's really messed up maybe you can sell that back and use the proceeds to buy a proper back. You'll probably also want to look for an extension bed. And new bellows. And a lens.
But otherwise, it looks perfect
