Yours is a .44 2nd (Note the absence of the ejector rod shroud)----came after the 1st (Triple Lock) and before the third, and just to keep things a bit on the confusing side was produced right along with the 3rd (Model of 1926)----up into 1940. Then for whatever reason, they apparently dumped their remaining inventory---39 2nd targets shipped to J.L.Galef Co. in New York City. I say apparently dumped because the 39 units were billed to Galef for what I reckon was the cost to produce the guns--------$17.00 each.
