This design was patented by Augustus Bennett on January 27, 1863 (reissue April 14) and produced by B. Kittredge & Co; originally as an accessory for the Frank Wesson rifles the firm was selling. The box was readily adaptable for use with the .44 RF cartridge (such as the Henry rifle, as described in Les Quick's book on the history of the Henry Rifle during the Civil War). Construction is solid brass with "B.KITTREDGE & CO. (partially obscured)/GUN DEALERS/CIN OHIO/PATENTED. JAN. 27. 1863/REISSUED APL.14. 63" stamped on the spring loaded lid, brass belt loops and nitre blued spring, and a round body.
