N.Y." marked just ahead of the rear dovetail, "40.90S.ST" on the bottom of the barrel ahead of the Schnabel style forearm, the forearm could not be removed at the time of describing, "8684" on the lower tang, the two-line Hepburn patent marking on the left side of the frame, and a checkered round knob semi-pistol grip buttstock with a checkered hard rubber shotgun buttplate.
