Actually Joe, Bernardelli is still in business today and they still build the same hammer gun. It utilizes the same action design but they have changed the engraving and stocking style (for the better IMO).
Here is a line up of Bernardelli's doubles.

They also made a run of a hammer gun called the "American West" (bottom) with the Italia Extra on top.

They even make high grade H&H type sidelocks.

I have owned a couple Bernardellis. One 20ga Brescia, one 12ga Italia Extra (w/ 30" bbls). I've also owned a "Mi-Val" hammer gun. It was identical to my Bernardelli guns in every way except for the engraving.

Also, that nice looking hammer gun that's listed on Gunbroker was not made by the same maker as the guns referred to in this conversation (which were made by Vicenzo Bernardelli). The one in the auction was made by L. Satina Bernardelli (cousins perhaps???). Same basic action though... although the 3rd fastener is a little different.
