This is a stunning example of the "Model F" No. 2 Brownie in a rare dark green leatherette. While the Brownie was famously "black and boxy," Kodak released a series of colored models in the late 1920s to appeal to more fashion-conscious consumers. The Model F was the first in the series to use a metal body rather than cardboard, making it much more durable. It features a simple rotary shutter with an "Instant" and "Time" setting, and three selectable aperture holes (controlled by the pull-tab on top). Most importantly, this camera is the reason 120 film exists today—it was the first camera to use that specific format, which remains the standard for medium format photography nearly 125 years later.
