Just received the camera and I must say it is V E R Y nice! John included some extra items that were not discussed and it got here SUPER fast! As much as I was disappointed with the Graphic View that I bought from the evil place, I am doubly happy with this purchase from John Koehrer! The rail is actually 26" long and it appears that there's a solid 22" from the back of the lens board to the film plane. Seems like a great camera for long lens work. Now, if I could only figure out how to open the preview on the 12cm f6.8 G. Leitmeyr Weitwinkel Anastigmat lens...
