Mr. Weiland published the second edition more than two years ago. I am not sure how a more exhaustive research for a book could happen beyond what Mr. Weiland did. He made multiple trips to Eibar, where he became great friends with several old noted gun makers, I remember a number of mentions of trips to see and talk with (and hunt with) Ignacio Urgartechea. The old school gun makers that befriended him were able to give him a wealth of information on "extinguished" small shop makers, much of which is in the book. I have corresponded with Mr. Weiland several times, he says he is in the process of researching a third eddition now, which will include much more on the fine Spanish Best over/under guns. Not to take anything away from the names you mention, but Terry has indeed done his homework, and done it well!!
