Want to Buy WTB - your excess film back for my pinhole project

I'm thinking a 4X5 film back attached to my ceramic pinhole project might be the trick that brings it to completion. Any ideas, junk, surplus, etc? Thanks in advance. I will need length and width dimensions on your stuff to figure out if I can make it work. Bill Barber

Hi Bil

Are you familiar with this guy? He plays with clay too.

No, I was not familar with him and his work is spectacular. Mine is a bit more primitive and that is being very kind to mine. Bill Barber
