This is a gigantic catalog of everything optical. Only the cameras and lenses are presented here, and, at that, is 115 pages. To add in the photographic lenses would be another 80 pages. Cameras include those made by Rochester Optical & Camera Co. (view cameras, Premos and Pocos), Eastman Kodak Co., Ray Camera Co., Blair Camera Co., Gundlach-Manhattan Optical Co., Folmer & Schwing Co., Century Camera Co. and others. Therefore it is a fairly comprehensive listing of cameras made in 1901, but notably lacking is the Anthony & Scovill Co.
