Hi There,
Welcome to our Group!
You have a S&W .44 DA (Double Action) First Model. It is mis-
sing the trigger guard and probably the trigger spring. These
were made starting around 1881 and were sold from stock up
to about 1913. All the frames were made prior to 1899 so it is
considered an antique under Federal Law.
S&W back then used numbers to describe frame sizes. The .44
size was called the Number 3 (.22's were No. 1's, .32's were No.
1-1/2, .38's were No.2's (except the Civil War vintage ones)).
It looks like it needs some TLC.
Cheers!
Webb
