Thanks for your interest.

The rifles are a proper pair. Alfred Gallifent has one of them and I will pass on your comments to him, as well as asking him to measure bore/groove.

Your comments are particularly interesting in that the mold (ball) that came with them casts a ball that is .760 which is the bore measurement and so that they are too large to be loaded; further, although the mold is of the period and numbered to the guns it is numbered clumlsely and marked 11/12 bore - so it is deeply suspect.
