Hi everyone just picked this up in a local shop here in Maine. British smooth bore musket bore is .732 barrel is 33 inches three barrel keys holding barrel Lovell catch for bayonet. What model is it? Looks to be some type of Sergeants musket? I am stumped. Barrel is too long for carbine or sea service musket. IN the ramrod channel are thre names Jackson, Wetherly and Barnett. Please see the photos and let me know your thoughts. Hoping the experts here will know.
