Patented in 1868 by Colonel G.H. Money and Mr. M. Walker, this rifle was one of the 10 finalists in the British breechloading rifle trials of 1868. It is a simple falling block system with an internal hammer. In the second set of trials, it proved to be middle of the pack in rapidity of fire (20 shots in 1 minute and 14 seconds) but succumbed badly to exposure testing. The Martini would win those trials, and the Money-Walker system was only used in limited commercial rifle and shotgun manufacture.
