Made by FN in Belgium, this Auto-5 16-gauge barrel assembly is identified by the St. Louis, Mo. & Montreal, P.Q. address style used circa 1959–1968. It is rollmarked "MADE IN BELGIUM" and bears Belgian proof and inspection marks along with a 16.8 metric bore stamp.
The barrel features a ventilated, matted rib that provides a flat, glare-reducing sighting plane, capped with a single front bead. The choke is fixed, with no additional choke system or tubes noted.
Designed for the Auto-5 long-recoil system, the assembly includes the integral barrel extension and barrel ring appropriate to this platform. An assembly or part-number style marking is present on the exterior of the barrel extension.
Constructed of steel, this barrel retains the period-correct markings and configuration associated with Belgian FN-made Auto-5 components from the noted era.
