I have a number of engraved SAAs. Going to sell a couple, but it is difficult to find others to compare. This one was made 1881, 44-40, restored and engraved by FEMA certified master engraver Swanson. The gun looks brand new with the exception of the perfectly fitted ivory grips that appear as old as the 1881 gun. Gun is nicer than the pictures show with the glare. Any ideas of fair market value?
