Stocks are of the correct style but are in better shape than the gun so that is why they may be replacements. It looks correct and if it functions fine, I would ask $1500 and wait for a buyer. 1000-1200 if you want to sell it this weekend. If it was 45 Colt, you could easily add $500 to the above figures. I was just shooting my 1908 Bisley 38-40 4 3/4 in a cowboy match last weekend. I like the cartridge. My Bisley looks like your SAA and I paid 1K for it at the Louisville show about a year ago and had to stick $100 into have the hammer and trigger rebuilt. But I waited a long time to find one for that price.
