Seneca Cameras, Seneca Camera Mfg. Co., (Rochester, NY), Catalog N, undated c. 1914, ~5"x8", 76pp

From 1906 through 1913, Seneca established a routine of publishing one catalog per, usually "numbered" using a sequential letter of the alphabet, and often also bearing a copyright date. For instance, Catalog L had a copyright of 1912, and Catalog M had a copyright of 1913.  It is a fair inference that Catalog N is for 1914.  The Camera City View changed its hardware this year to become Camera City View Variation 2.; the top engraving on page 32 is of Variation 2, while the bottom engraving was not re-drawn, and still shows Variation 1.
