Unfortunately they didn't. However they did have a picture of the right side of an engraved Model 44, the single action pistol. It is probably the same one illustrated on the cover of the 1955 Gun Digest. It looked about the same as most Model 39s, except the extractor was a long, slender piece, with a tongue at the back that fitted in a groove in the slide. It did not extend back as far as the Model 39 'no dash' extractor. It looked a lot like the extractor on a Mauser Broomhandle, particularly one of the older ones. Is this common among the 'prototypes'? I wonder where both of those pistols are now? S&W museum?
