Hi There,
Welcome to our Group!
The revolver pictured is a S&W .38 Double-Action (DA for short)
2nd Model. These were made between 1880 and 1884. The
serial number range is 4001 to 119000. To get a more definite
date, you will have to get a letter from the S&W Historical Foun-
dation. The letter will only tell you when it was sold (not speci-
fically when it was made). S&W didn't keep records of manufac-
ture dates back then.
Cheers!
Webb
