Hmm, I actually think whoever did the work did a nice job fabricating and fitting the rib to the barrel.
The height of the sights is right in line with what a lot of people used in the 50s and 60s for bullseye competition if they shot revolver.
Sterlslaver had a good take on how to address the top strap and rear sight.
At least it didn't get an overbuffed rebluing with the usual sideplate fitting issues.
