I've just begun another .54 cal GPR, but this time I started with what for me seems the most difficult furniture item to complete: the trigger guard. Frankly, I'm always surprised by how steel coated with dull, tenacious, foundry scale will eventually develop such a lustre. I browned the previous GPR's furniture, but this time I'm considering leaving it in the white & allowing it to naturally age (with proper maintenance of course).
I have two (TC Hawken & 1853 Enfield musket) with brass furniture, & I don't mind polishing it during the normal cleaning following target practice, etc. Old habits die hard, I guess. However, I believe there's viable merit in allowing brass & steel furniture to develop its own patina. The aged appearance seems to compliment an already beautifully designed firearm of a century or two ago. As with being historically correct/period correct, so long as the firearm is well-maintained, then its ambiance, as it were, should be the decision of the owner -- bright & demerit-free for those who are avid re-enactors perhaps, & whatever is pleasing &/or practical for anyone else.
A buddy of mine has a half-stock that looks like it spent three years in the Rocky Mountains with its nicks, scratches & abundant patina. It's gorgeous! Could I do that with mine? Probably not. Again, old habits . . . & values. It's whatever winds your clock or floats your canoe.
