Catalogue No. 31 of Cameras, Kodaks, Lenses and Photographic Accessories 1926-1927, Central Camera Co. (Chicago, IL), dated 1926, ~5½"x8½", 288pp
This catalog, apparently in force for two years, actually overlaps with Catalogue No. 27 1925-1926. One mystery is what were Catalogues 28, 29 and 30? Despite its nearness to No. 27, Catalogue No. 31 has 12 more pages and a different layout than No. 27. However, the lens data is virtually the same, and the roll-film cameras - well, who cares?
