MR743 SMITH PATENT PERCUSSION CARBINE IN .50 CALIBER; The 21-5/8 inch barrel has an about good bore that is bright with strong rifling, and just a bit of light to moderate pitting here and there. The metal is smooth overall with the barrel finish a freckled gray patina back to the carbine band and about 70% blue turning plum brown from there back. Light traces of case colors on the frame give it a modeled nickel appearance. Original sights and sling swivels. Walnut stocks show plenty of use having the typical bumps and bruises, a small chip is missing at the toe, but otherwise are solid and may have had a light coat of finish added a long time ago. A real nice example that has some character.
