"The few Hawkens in good enough condition to see original barrel finish are blued. The blue is fairly dark. I like the color I get by doing a satin slow rust brown, followed by boiling the barrel in water to duplicate the color. When doing the rust blue, don't overpolish or you get too bright a color. It is not the deep translucent blue seen on European guns. The rib and thimbles were also blued.
The breech and tang were case hardened as well as the lock, butt plate, trigger guard, trigger bar,entry thimble and nose cap. Not the highly colored case of modern firearms but a mottled grey case that some of the early makers called forge casing. "
