High Wall, thanks for your interest. There are no markings on the barrel at all. It is a 14" twist. It's 26" long, tapering to .730" at the muzzle. The machine work looks to be first class. There isn't a trace of ripple from end to end. You're welcome to look it over and return it if not satisfied. Should you need a new Turkish walnut forearm with ebony tip and a one panel point pattern checkering, I'd give you a good price on it.
