There was a period of time early in my career at USFA that we stopped doing business with Turnbull. After a short period of time, all was well again but in the mean time, frames and hammers were sent to Classic Guns in Beecher, IL for color case. Classic used slightly different ingrediants in their process and the frames came back with alot of straw colors, reds, blues, etc. I could be wrong but this looks like a Classic gun to me and nothing like Turnbull puts out. There aren’t many Classic guns out there perhaps a few months worth.
