Belgian manufacture and Liège proofing confirm this as a FN-made Auto-5 component from the classic era. The St. Louis, Mo. & Montreal P.Q. rollmark further identifies it as pre-1969 Belgian production, aligning with the stated 1959–1968 timeframe and the Made in Belgium marking.
The chamber is clearly marked 12–70, indicating 2.75 in shells, and the bore mark of 18.5 mm is present on the barrel. The Belgian factory choke code "*-" denotes Improved Modified, offering factory-verified constriction appropriate to this period barrel.
It features a ventilated rib with a matted rib plane and a single brass bead front sight, providing a traditional Auto-5 sighting setup. The smoothbore carbon steel barrel wears a blued finish consistent with the era.
The Auto-5 barrel ring/lug is present, and the barrel extension shows an assembly/part number (not a receiver serial). Markings include the Liège crowned ELG oval proof, Perron proof, and controller/star stamps, along with the Made in Belgium and St. Louis, Mo. & Montreal P.Q. rollmarks.
