It has standard S&W factory markings with a Canadian "crown/30" stamped on the butt, matching assembly numbers on the yoke and crane and matching serial numbers on the butt, barrel, right grip panel (in pencil) and cylinder.

Excellent. The revolver retains nearly 98% original blue finish showing some patina speckling on side plate and a light cylinder drag line. Most of the original case colors remain on the hammer and trigger. The grips are also excellent with a few minor dings and scratches and crisp checkering overall. Mechanically excellent. An exceptional example of the military .455 model.
