Hi Hawg, I think you nailed the finish, bare polished steel. I put some Brownell's Oxpho Blue on the recoil shield of the revolver, it blued immediately just like bare steel. I took some vinegar followed with Flitz polish to remove the bluing. I suspect that the revolver will patina with use to look like an old revolver. The original Colt charcoal bluing was thin that wore easily and turned grey with time. This revolver may be a good candidate for antiquing.
I received a reply from Pietta that they will answer my finish question after they return from Christmas vacation, 01/08.
I did find one minor issue with this revolver. When putting ant-seize on the nipple threads, there were two nipples that were not fully installed and could be removed with finger pressure. The other nipples were only lightly seated.
I'm considering adding a taller dovetail front sight, but since I already have dialed in 1851 shooters, why? Maybe just leave the revolver stock makes the most sense?
Regards,
Richard
