"When Lovell designated the butt box, he apparently intended it for greased patches and a piece of rag for wiping the barrel. In January 1839, however, Maj. Boileau submitted a design for a large rectangular cavity with a turn catch or button to hold the implements, and a smaller round one for the patches or grease. Although Lovell objected, this large trap, six inches long was adopted. The butt box involved two compartments, one to hold loose patches and the other set up to secure a three armed combination tool." referring to the Two Band Brunswick Rifle development.
