In addition to the questions regarding the I.J.A. & C.W Target Sealed 8 pistol that I posted earlier, I also have a Stevens Model 621 pump shotgun that also belonged to my grandfather who passed away in 1947. I forgot this item earlier when i said that all I had from him was the pistol and the straight razor. At any rate, can anyone tell me about this gun? Where can I find the serial number to determine the date? From what I have read here it apparently was made in the early 1900s. Thanks for any help.
