For instance, Catalog L had a copyright of 1912, and Catalog M had a copyright of 1913.  Were this to continue, Catalog N is for 1914, Catalog O is for 1915, Catalog P is for 1916, and Q is for 1917.  The catalog has gone from 72 pages in Catalog P c.1916 to 48 pages here c.1917.  No more six or seven pages devoted to a view camera model.
