The Brownie that I ultimately wore out was quite similar to this updated version which was on the shelf about the mid forties. Mine was a brown leather-covered model that I cannot identify as to an exact manufacturers date. However, it could go back as far as the turn of the last century.
The release leaver is in the same spot. See lower left top, just under the advance knob. . The size is about the same and there is a bit more shinny metal trim. The aperture setting on the old box was simply a slide out piece of flat metal with three different size holes.
So much for my first camera. I always hesitate to tell people what brand of camera I use because better cameras do not necessarily make better photographs. "Art comes from people, not tools." I dd gravitate to a higher quality level 2 1/4 and a 4 x 5 view camera. These were well made and they have lasted to this day with no broken parts. That represents more than thirty five years of heavy use and being carried around in a home-made back pack when hiking the Blue Ridge and Allegheny Mountains.
