The No.2 Brownie is a simple box camera with a very dependable shutter. It has two sliding mechanisms on the top, one for a bulb, or time setting, and the other for a choice of 3 apertures. It also has two small reflecting finders for vertical or horizontal shots.

This is a Model F, dating from 1924-1935. This model has two innovations that make it particularly valuable/useful: it takes 120 film which is widely available (earlier versions took 116 film which is obsolete) and it has a tripod bush.
