Hi, the round barrel 1851 arrived today. It is indeed a Navy Arms 1851 barrel. It fit perfectly on my Dance, well sort of. The barrel arbor hole is deeper than the one on the Dance and would need internal shims to have a solid barrel lockup. Also, while the barrel bore is sharp and clean, the exterior finish is "b" grade. I'm a f--ing perfectionist when it come to my guns so I ordered a new Pietta .44 round 1851 barrel from VTI.
I thought of refinishing the Navy Arms barrel, but would still need to address the deep arbor hole. Maybe a project for another day.
Regards,
Richard
