Do you have the box with the end label? I don’t see a BFY in the 5th Edition. My 60-7 was 1993 according to the Spec Ord code. Mine has wood service stocks with the flash chromed hammer and trigger. I bought it new in ‘93 or ‘94.
I had another 60-7 that had Spegel Uncle Mike’s boot grips with the case hardened hammer and trigger. I bought it new around 1994 IIRC. Kind of odd but that’s S&W…
