I took this nickel 357 SAA NF in trade for some WW2 firearms. I know a lot about WW2 firearms but near nothing about SAAs. I sent for the letter back in May so I should hear from that soon. The Colt DOB data base says 1961. The fella I got this from said the stocks are real and expensive? They look authentic to me. I joined the forum to benefit from your collective knowledge. Please take me to school on this...curious about true value, rarity (I assume pretty common), all S/Ns match- 4293NF I know it is a Gen 2....
