Mike -- I'm sure that coming from a builder as good as yourself Chuck would take that as quite a compliment.
He has actually built a number of guns in that style with the fowler hardware and "smooth rifle" type look, but I don't know about this particular one. I know his most typical builds are 50's or 54's and most are rifled, but he has built some with straight rifling etc too.
Chuck's website used to have a link to a photobucket site with hundreds of photos of his rifles he has built, but I can't get to most of the photos anymore. I think there are still maybe 20-30 photos.
He does a nice job - his guns have a distinctive look.
