I'm looking for advice and opinions about a used 20 gauge shotgun at a gun shop. I've found little real info on it except in one book, which says that there are or were three "Bernardelli" manufacturers: Vincenzo, Pietro and a third. Only Vincenzo Bernardelli guns appear in the listings. The only remark about Pietro Bernardellis is that a bunch were "dumped" in the market in the 1980s. Is a Pietro Bernardelli even worth purchasing for limited hunting use? This is a clean-looking little gun with some engraving and walnut stocks. Thanks.
