I recently inherited a muzzle loading rifle. The only barrel markings are "Made in Belgium" on the side and the name Turner Kirkland...Union City, Tenn. stamped on the top. A quick caliper reading says .490 bore so I am assuming a 45 caliber. Also
the is a stamp "5C1" on the trigger guard. I was wondering if that is enough information to find out when the rifles were made and possibly the rough value. Thank You for your help.
