Greetings, all:
My dad just gave me his old Browning Auto-5 shotgun (Thanks, Dad!), and I'd like to know more about it. I'm particularly curious about when it was made.
The gun's in excellent condition, with only the slightest thinning of the blue on a few edges. It's a 20 gauge with a 25-inch vent-rib barrel (seems an odd length), and the round grip-cap shape at the end of the pistol grip typical of the older guns. The trigger's gold-plated, and the triggerguard appears to be anodized aluminum. The pistol grip and underside of the forend are checkered, and the wood has a shiny finish of some sort. At some point someone added a Pachmayr recoil pad. It also has 1-inch sling swivels fitted, the rear in the usual place on the buttstock and the front mounted in the center of the magazine end cap.
The gun has relatively few markings on it, mainly on the left side and bottom. On the left side of the receiver, it has the script lettering "Twenty" and below that the conventional lettering "Browning." On the left side of the barrel at the chamber end are two lines of lettering and symbols. The top line is pretty self-explanatory:
FABRIQUE NATIONALE D'ARMES DE GUERRE HERSTAL - BELGIQUE
The second line is not so clear what it all means. It starts with two small symbols I don't recognize (sort of like asterisks, but that's not what they are), then:
ACIER SPECIAL - C.20 - CART. 2 3/4"
and finishes with several symbols that look like proof marks, as you'd expect on a European-made gun. I assume "C.20" stands for 20 gauge, and "Cart. 2 3/4" is pretty self-explanatory. Any ideas what "Acier Special" means?
On the underside of the receiver at the rear end of the magazine tube are two lines:
4Z FN
777xx
I think the 777xx is the serial number, which should make this a 1928-ish gun. "FN" presumably stands for Fabrique Nationale, but I don't know what the "4Z" means. It doesn't correspond with the serial numbering schemes on Browning's Web site or at proofhouse.com. Is this perhaps a rebuild mark of some kind?
The 1928 serial number seems odd to me. The gun seems in far too good a condition to be that old. Maybe it's been reblued, but if so, whoever did it knew his business--all the markings are clear and crisp, all the lines and edges are straight and sharp. Might the thing have gone back to FN to be redone?
For a little history on this gun, my dad bought it in France in 1965. He got it used from the base rod and gun club at Toul-Rosierres (sp?) Air Force Base when De Gaulle kicked the Americans out of France and the base was closing. As far as I know, he never changed anything on it. He has always described it as a light skeet model, though it has no markings on it that say that (unless that's what "Acier Special" means). The bore inside diameter is about 9/16" at the muzzle; I don't know what choke that translates to. Oh, and it's a fixed-choke gun--no screw-in choke tubes or muzzle devices on it.
Any info would be greatly appreciated. I'll try to get a few pix up later.
Thanks, and Semper Fi.
