Thanks Daryl. Like you, I believe the barrel is a nice reproduction of an English style percussion fowler. With no real information coming forth about this barrel, I am guessing the markings may be a date(?) 2-5-84 and possibly the initials of the barrel maker or original owner. After flushing and cleaning the barrel, it appears never to have been used. the breech and flash channel were filled with bug remains and dust as if stored upright since it was created.
Barrel ID is not overly important, I was just wanting to know if anyone is familiar with the stamps. No information has come to light.
Thanks again, Dan
