Hayes had all the clothing and artifacts in his studio while he sculpted. Everything is authentic. Accessories include suspenders, a bandana and a badge plus the basic items Rangers carried at that time a knife, sidearm pistol and rifle. That way he only needed to carry one bullet. The color on this sculpture is an added bonus, and it's a lengthy process to achieve just the look Hayes wants.
Different chemicals produce the different shades of color.
It's like in ceramics, when you apply different chemicals to get different colors, but there you can't see the color until it's fired. With this heat-applying process, Hayes says they are able to actually watch the color appear in the bronzes. Bronzing of a typical sculpture will usually take half a day at the foundry. It looks like something other than bronze. That's why the faces and hands are bronze.
