At the time this gun was made by S&W, there were no "factory engravers" employed by the factory. S&W relied on their distributors to supply customers with any requests for an engraved S&W, therefore distributors , like J.W.Storrs, etc., contracted with various engravers for their work engraving guns for customers. The posters gun is nicely engraved and well done by someone skilled in engraving. Who that was is probably a guess, at the best. I see evidence that the style is in the work of Nimschke's shop, but not by the master himself, in my opinion. The pulls of Nimschke's work on S&W Model 1s are much more elaborate and delicate, with overlapping scrolls, and background shading, etc. Many different engravers in NYC at the time could have done the work. Having said that, don't forget this gun is an aftermarket refinished gun, as necessary for any gun engraved after it left S&W. The poster hasn't told us if the assembly codes are matching on all parts, but I'm assuming that probably are and that the gun left S&W as a plain nickel plated gun, not as a "Pinto" which was created after the engraving by blueing the cylinder. I would agree with the estimated of current value. Ed.
