This Kodak Brownie No 2 camera had a long run and was introduced in 1901 then discontinued in 1933 with the Model F being released in February 1924. Model F has an aluminum case that replaced the cardboard and a tripod socket added. The No 2 also was manufactured in the UK from 1928 till the end date of production. The number of cameras sold and produced is not known but over 2,500,000 before 1921. The camera uses 120 roll film to give you a 2 ¼” by 3 ¼” picture. The No.2 Brownie is significant in that it was the first camera to use 120 roll film. It is a very simple camera with a very dependable rotary shutter. It has two sliding mechanisms on the top, one for bulb setting, or timed, and the other for a choice of 3 apertures (about f8, f11, and f16) that sit in front of the Meniscus lens. It also has two small reflecting finders for vertical (portrait) or horizontal (Landscape) shots. The original price was $2.00 with the aluminum model F selling for $2.75 and the color models for $2.50.

Others have reported the apertures closer to f/16, f/22, f/32.

I have film in mine now, so can't measure them. The camera manual says never to use the smallest aperture with instantaneous exposure. Obviously the never considered ASA 400 film.
