I bought this a while ago with the idea of building a 7x11 camera, figuring the back and holders were the hard parts so this would give me a big jump and the rest would be easy. While that's theoretically true, in reality the project never got beyond dreaming/planning and I finally bought a complete Eastman View 2 when it became available. I really don't think I need a spare back, even though it fits perfectly. The external dimensions are 12-11/16, and the pins are a shade under 11-1/2 center-to-center. It's in decent shape, with the nicks and marks you'd expect from nearly a century of use. Two of the clips that hold in the ground glass are missing but the rest of the hardware is present. The gg is OK - it seems home-made and has some small clear spots you can see in the photo, but it's certainly usable. $140 will get it to your (US) door. International shipping is likely to be painful - contact me and we'll see if we can make it work.
I know where there may be a couple of holders for sale, but don't know for how much.
