The basis for EMF's "1851 Pepperbox" was a handgun found by Herb Houze (the Colt/ Winchester authority) in Canada in the 1970s, and was then owned by a collector named Jimmy Fielder. It was made by attaching a barrel cluster of the Blunt & Syms type, about five inches long, to the frame of a Colt M1860 Army. Its present location is unknown, but there are other handguns of this kind in existence. One such gun, a double-action percussion Bentley, with a revolver-style frame and a typical pepperbox barrel cluster, is shown on Plate 11 of W. C. Dowell's "The Webley Story" and undoubtedly there are (or were) others out there as well.
