Catalogue of Photographic Apparatus and Supplies, No. 72, G. Gennert (New York, NY), undated c. 1919, ~6 ½"x9 ½", 128pp
This is an undated catalog, although it has the catalog number 72. The latest film offered is No. 127, introduced in 1916, but the catalog is probably a few years later than that. Gennert did not start numbering their catalogs until at least after the 1900 catalog, which is not numbered. The undated but c.1906 catalog is No. 58, and the 1921 catalog is No. 74. Assuming one per year during 1919-1921, this catalog is probably c. 1919. The two view cameras in this catalog, the New Improved Montauk View and the New York View, appear to have been purchased from the Seneca Camera Mfg. Co., and appear to be identical to that company's Seneca View, Improved and the Competitor Variation 1, respectively. The covers are missing.
