Re: Looking for manufacture date for a S & W
That serial number would not jibe with either the .38 DA Fifth Model or the .38 Safety Fifth Model. Going by the serial number, and the fact that the safety models had a concealed hammer and no flat on the trigger guard, I think that gun is the .38 Double Action, Third Model. Some 203,700 were made from 1884 to 1895 serial numbered 119001 to 322700. 164401 would be toward the earlier date, so that one was probably made around 1886. Value even in good condition is low, since so many were made. I would doubt that gun has any real value at all; cleaned up and repaired as necessary it would be a usable gun, but those old guns are subject to breakage and not reliable.
At best, it might be trade material on a newer gun.
