The first book is "Maxim Nordenfelt Guns" (English), and the second is "Canons a Tir Rapide et Mitrailleuses Maxim-Nordenfelt" (French). Both have labels from Whitehead, Morris & Co. inside the covers, and the French book has a Henk L. Visser bookplate. They provide excellent information on the Maxim Nordenfelt naval and infantry guns of the late 19th and early 20th centuries as well as the legendary Maxim machine guns. Maxim Nordenfelt Guns and Ammunition Co. Ltd. was formed by the purchase of Thorsten Nordenfelt's company by Hiram S. Maxim in 1888.

The first book is good with mild age and storage wear, a few notations in the text, and limited minor staining. The second book is fair with a separating front cover and otherwise mostly similar mild age and storage related wear, a few notations, and minor staining.
