I believe alanint is spot on. I too looked at that barrel and thought salt blued. The interior of both should be in the white steel, like one of them displays. A lot of times if it is a "bubba blue" , the edges would be rounded too much and the safety not painted in. When you look at the flat surfaces, they wont look "flat" but wavy reflecting light. A bubba blue is easy to spot, yours looks better than that, but a reblue for certain. Also, they should have a rainbow or step strawing/fire blue color on the top of the hold open, not the spring that should be white.
