not on any of those. numrich has the part listed for the 720 and 971 as the same. new rossi makes a R97104 which looks like the old 971. same gun, caliber... etc..... I think I might have to risk the $10 for their new gun hand to see if its a mate. before I do that I was hoping for some more positive leads..... all the googling I do leads to dead ends. the timing isn't a problem now I just want to be prepared just in case. I've already secured two sets of firing pins, springs, and rivets.
