Conley Camera Co. / Sears, Roebuck & Co. Catalogs
The history of the Conley Camera Co. is presented at http://conleycameras.sevenels.net/history.html. Briefly, the company was founded in 1899, but didn't blossom into national importance until 1907, when the Rochester Optical & Camera Co., who supplied photographic equipment and materials to the huge mail-order company, Sears, Roebuck & Co., was purchased by Eastman Kodak Co. Sears apparently couldn't come to terms with Kodak and thenceforth carried Conley products, an association that resulted in Sears' purchase of Conley in 1924.
Prior to the 1907 switch to Conley, Sears contracted with various manufacturers, including the Rochester Optical group of companies (e.g., Perfection Viewing Outfit) and the Century Camera Co. (e.g., Seroco View Camera Variation 1). The cameras of this era, whatever the manufacturer, bore the brand name Seroco (ever so cutely derived from the first letters of Sears, Roebuck & Co.).
