Anyone know these custom repro BP rifle builders

1.J. Hall, I believe it is John, Jon, or Jack, it is a t least 60" long overall and is 45 cal caplock with full stock.

2.Harvey L. Underwood Evensville In., it is at least 60" long, 45 cal., flint, and fullstock but the barel is on at least 1&1/8" flats!!!(really heavy)

3.Paul R. Jones 1992, it is at least 60" long, 45 cal., flint, and fullstock.

Anyone know these makers and an idea,ball park, as to the worth of thens rifles.

The Hall rifle has extensive relief carving and inlays, even an ivory inlay with an eagle scrimshawed on it!

I WILL POST PICTURES AFTER THIS WEEKEND WHEN I QIUTE HUNTING IN OHIO!!!!!!!!!

Thanks for any input at all.
