Hi There,
Welcome to the Forum!
Your revolver looks to be a S&W .44 DA 1st. Model. From the
look of the cylinder, I think yours is the "Frontier" version.
These have a longer cylinder (1-9/16" long) and were cham-
bered in .44-40 (a.k.a. 44 WCF). The standard length cylinder
is 1-7/16" long.
These were not a good seller and many were converted back
to .44 S&W Russian (by replacing the cylinder).
The .44 DA 1st Model came out in 1881 and the "Frontier"
came out in 1886. All were manufactured before 1899 and
are considered antiques. As I said, these were not good sellers
and were sold from stock up to 1913.
Cheers!
