If there are no pictures, I.............
If there are pictures, the gun is a Joseph Manton owned by a friend who is only slightly older.He uses it for squirrels with black powder of course.The barrel has been repaired about five inches from the muzzle. He pulled the plug and says there is enough metal left.He could be correct.

Anyone care to place a value on it ?

Could anyone give an estimate of its age ?
