This is a No 2. Folding Pocket Brownie Model B, made by Eastman Kodak. According to The Brownie Camera Page, mine is a late model because I have black bellows, the metal lens mount, and the long hinge.
This is the most valuable camera in my collection, but only to me. If I had save two cameras from a fire, it would be this one and my original AE-1, which was a gift from my parents. And this one would take precedence because I've got more AE-1s. This was my paternal grandmother's camera, and she got it new so it's been in my family for a century now. It's famous in my family as the camera my father "fixed" as a child by oiling the shutter with sewing machine oil (tip: camera shutters don't like oil. They're like watches, they like tiny dabs of special lubricants that stay put), and my grandmother paid $10 to have it cleaned, which was probably what the camera was worth at the time.
I didn't realize it until I was doing the research for this page, but this camera takes 120 film. For some reason I thought it took 116, which is long gone; but I can get 120 at any camera store. So maybe I'll run a roll through it sometime and see what I get.
