Friends:
From a report I prepared on a Parker GH in 2004, which sported ARMAF barrels.
"The excellent condition 26” fluid steel barrels are serial numbered to the gun, but are non-factory, and no identification markings are evident on the exposed portions. They are evidently of skillful workmanship. They are equipped with a brass bead and a large file cut top rib. The bores are clean and bright. The chokes are not marked, and they were not gauged. Standard factory barrels for a GH Grade circa 1896 were “fine Damascus”, typically “two iron” Damascus. The current fluid steel barrels bear standard Belgian post 1924 proof marks, including the “Lion over P.V.” mark, the “Horseshoe” chamber /gauge mark denoting 12 gauge and 70mm (2-3/4”) chambers. There is also the proof year date code, a lower case Greek letter “gamma”, indicating the proof year as 1950. The barrel inspectors mark is “Star over V”, indicating inspection by Isador Macon. The name “ARMAF DAGUN” appears on each barrel flat, as well. Reportedly, Armaf was a well-known 1950’s era Belgian gunsmithing firm which did a large trade in rebarrelling quality American double barrel shotguns."
I have seen several guns sporting ARMAF barrels.
