I have inherited a S&W 22LR single shot and am uncertain of age, model number, value, etc. It has a 10-inch barrel and the last pat date appears to be Sept. 14. 08 (or 09). SN might be 4608. I say might be because that number appears on the underside of the sight/latch. I'm hesitant to take off the stocks to look on the grip frame because the grip is a complicated three-piece affair with what looks like an elongated wooden Tyler T-grip that extends below the butt and is fastened with two wood screws into the checkered, bronze/gold medallion, diamond wood stocks. I believe it is a Third Model, since it will fire DA. It is in great shape with very little evidence of handling or firing. It came to me wrapped in a rag inside a crumpled old kraft paper bag. It was given to me by the widow along with a beautiful mid-30s SA H&R Sportsman which my kids and I have been shooting regularly. She gave a Colt SAA and a Reising 22 pistol to a closer relative. The safeful of Browning Superposeds she sold to a dealer without consulting us.
