Trying to I.D. a 12ga. percussion SxS I found in a gun shop . Approx 28" Bbls , blued , walnut stock with checkering on the wrist . No markings on the Bbls on top , but under the fore-end , its marked "made in Italy" , there is a "0"stamped on one barrel , and a "4" stamped on the other ,Only possible makers mark I could see was "BN" in a box , the rest appearing to be proof marks .Obviously a repro. ,but I believe pedersoli is the only one making SxS's now , and the gun doesn't appear to be that old , and no choke tubes .Looks to be in very good condition. Asking price is $400 . Thanks in advance for any help-----Jerry
