That star stamp is not the S&W mark of a reworked/refinshed gun. Having once done a bit of gun etching myself, I can tell you the work was not done by an amateur. David compares it to the style of one of the Young's and that is quite possible. If the etcher used a gun engraved by them as a pattern source, it would have been a quick & easy way to recreate the Young style by etching and not engraving. At the time this was done ( circa 1888 ) there were probably more journeyman etchers working than engravers, as etched glassware, etc. was very popular. Ed.
