Have been following this with interest. Back when I was young and had better vision and digital dexterity I changed out several sight blades with only one leaping spring (which I actually found.) now I regard the whole process right up there with a root canal or colonoscopy! Great find and great save on your 66-1, which I personally regard as best of the breed. My only negative would be your nephew’s choice in grips. All of his taste seems to be in his tongue! That gun would be sheer perfection with a set of factory smooth combats with finger grooves. Then it would be total perfection.
