Blair Stereo Weno
Blair was one of a number of companies absorbed by Eastman around the turn of the century. Built in the popular "pocket" style, Weno cameras are less common than the similar Hawkeye models, and were only made in 1902-'03. Although still labeled Blair Camera Co., Kodak would drop the Blair name around 1908. I believe this is a very early example, as all the others I have seen have an aperture scale bridging the top of the gap between the shutters. Blair Camera Co and Weno are then stamped into the black metal cover. On this camera, Blair Camera Co is stamped into the two small chrome plates screwed to the tops of the shutters. The only number I can find on the camera is an 88 stamped under a film take up spool. I'm guessing that is the serial number.
