Hello, first time poster - I've recently acquired a gun that I'm not familiar with. I posted the information on a local forum, and a fellow dated it to around 1915-1916. I don't know if it's a Bekeart or not, but I'd like to find a rear sight. I'm not having any luck on parts sites and auction sites, and I was directed here for advice. I've been told the Bekeart models had a different rear sight than the non-Bekeart. The leaf would appear to need to be about 3/16", much thinner than my other S&W revolvers. I'd like to just get any rear sight that fits that would make this functional. It's far from perfect so just being able to take it out and shoot it occasionally is the goal. It was listed as a parts gun, but I think it's too good for that and deserves to live on. Serial number is 225138, cylinder is stamped with the same number. Thanks in advance for any help.
