I also have tried to find information on a 12 ga. sidelock, assisted opening, chopper lump barrels, Greener cross-bolt, ejectors, Anson type forend release. Serial # 6125. Written on gun Fabrique Nationale de Armes, de Guerre, Herstal Belgique. 72cm barrels, (28 1/2"), 65mm chamber (2 1/2"). Went to the web site for FN, emailed the U.S.A. sddress and the email came back with a 4 word response, "No informaton on gun", couldn't even take the time to tell me where to look. Then tried FN in Belgium, email came back "no address found". Also tried Browning site, if you want to call it that, everthing is like a mystery there. Couldn't get information there either.
A few people on this site gave what information they could, but could not find year of manufacture. Geno said of the ones he has seen, in his opinion weren't that good. I can't believe a gun with those features is not a well made gun. I would just like to find somewhere a site or book on these guns and the different grades. Now it's getting to a point where I really want to find answers on these guns, why so much mystery?
Good luck and keep us posted if you do find information, maybe you will get lucky on the FN site.
