I hope to have the camera next week and I'll post photos as soon as I receive it. I used an 8x10 Sinar C, (C2?) as a base. It has a P rear standard and an F2 front and I got it VERY cheaply. Richard used a 7x17 back from one of his new cameras and a 36 inch bellows from Camera Bellows in England. I currently use a 4x5 Sinar Norma (I don't backpack) and really enjoy the precision and ease of a modular monorail. I don't think the 7x17 is going to be a problem for me to move around, but I use a Sherpa Cart to transport my LF camera gear so a little extra weight and bulk don't matter to me.
