Reblued is not the end of the world. But......metal prep was extensive ("skeet unreadable"), though. One set of barrels doesn't ring/rib loose? This is sounding familiar. Maybe bluing salts got left in the channels? Maybe barrels are alot worse than you imagine, ie., rusted through? Other set of barrels was reblued at same time, by same outfit?

My money.......$3000. More than that involves too many optimistic assumptions.
