It's one of a line of Century Graphic studio cameras. Tough to tell what era, but my guess is the Folmer Graphic version from around 1900-5, though they came with various labels from Graflex and Eastman Kodak since the whole industry in Rochester was in flux at that time. An elaborate version for a large studio is shown
here. I have one that I bought in about the same condition as that one appears for $50, without any lens or that very useful, if ungainly, stand. These are real studio workhorse cameras, often still quite useable since the bellows is pretty much bulletproof rubberized canvas and they were built to last. The back is a sliding splitter that allows two images on one negative. The stands alone go for about $400, though I have seen them from $100 to $500. Refinished, these things are beautiful, big and comment-producing. That's why many of them have turned into "display models" over the years. A few years ago an 11 x 14 version sold at the PHSNE auction, with multiple adapters to fit 8x10, full plate, 5x7, etc.; two lenses, a beautiful oak, iron and brass stand and two air operated shutters for under $250. I had no room for the beast, but I still try to get the person who bought it to
use it instead of decorating her living room with it!
