Thanks everybody. Sharps4590, the John Manton pictured is from approx. 1830, rather late in the game with all of his latest details. A friend and I both remarked how light the double barrel was. I cannot remember the exact weight. Here's the inside of the John Manton locks and breech. I think some models of the Joseph Manton locks are a bit different.
