A fine machine.Back in 1951 when I first got interested in muzzle loaders I came into contact with P.I.Spence in Marietta,Ohio who was probably the first to offer a usable lock and trigger for a new made muzzle loader and we talked about this type of rifling machine and he had one from an old shop and rifled a few barrels with it and then made his own with a reciprocating slide and said "My machine goes back and forth and I sit and watch it".This one is a fine representation of those seen in some gun maker's shops and represents fine work.and skills.Enjoy the benefits of walking short distances.
