I have located Andrew Kennedy, my 3x grand father's, musket. I am told it is a .58 caliber. It is in the Sam Houston School House Museum near Maryville Tennessee. Andrew used it during the revolutionary war in 1780 I have some photos & would love to know more. It appears to be home made to me and I have in on good account that Andrews father or grand father brought it to the US when he immigrated Can someone assist me please?
