I work at BW and have known Kevin Wardle for a long, long time. He is indeed a master of 1911's. FYI: He is no longer up at Black Wing. He actually switch career fields, but is still doing some gunsmithing on the side.
Good luck with the sale! Seeing as I have 4 Wilsons for my 1911 needs, I don't need another 1911, but it is definitely done right since Kevin's touched it!
