I was able to pick this up from a recent David Carroll auction. A Smith & Wesson .38 DA Perfected Model. Story is it was used by Winchester as a test gun. The right side of the frame is engraved W. R. A. Co Reed 4/20/17. At some point it was given the 'Fitz' treatment. The trigger guard was altered, the hammer has been bobbed and serrated, and the rear latch was removed. It is a shame that that is all of the history that I know of this interesting little revolver.
