Unfortunately, my PM was sent before Mr. Shaw posted (and there may have been someone in front of me yet)!
So that I am not a piggy, I would be willing to take the 6x7 only, if Mr. Shaw really, really, really, really, really wants the 6x6 back and will actually use it. I have a project in mind for a 6x6 back on a 4x5 camera, so I would also not mind keeping the 6x6 and letting him take the 6x7. Hey, we are both in L.A. too! Imagine that! We could save on shipping by having them sent in one box.
