Larry, Ben, et al,
A posted list of spare parts available would be great! I mean I have friends who convert old polaroids into view cameras. Second, I would be interested in the lab service as well. I've been developing my 4x5 film in a Yankee box tank with poor results. Weak processing along the edges, a common problem I guess - been trying to locate a stainless real but they are hard to find and a bit expensive too.
Happy trail,
SteveP
