I'm going to completely restore a Westley Richards boxlock that was a simple "gold name" action. Lots of smooth, non engraved components to the gun.

Questions:

Would all components that were not color hardened been subjected to the same bluing solution?

What color is period correct: flat black (blacked furniture), blued, or "nitre blue" (what I would call indigo or purple)

Bonus question:

What colors should I request when it is rehardened to be correct for the gun? More straw, yellow, honey, and orange OR more blue, purple and chocolate?
