15" Graflex tele-Optar. I've only used my a handful of times but it's always been a pleasure to work with.
Big lens though. I recently bought one---haven't shot with it yet because I don't have a lensboard to fit, but when I unpacked it I experienced a certain amount of "OMG, what have I done?" angst. I guess it's not really intended for handholding, and in the context of carrying a tripod around it doesn't add that much bulk, but it's a pretty intimidating hunk of metal.

The lady of the house has to be a pretty swell sort of person to put up with the annoyance of a photographer.
