Both guns started as S&w 1911s were customized by sk guns in a limited of 500 series. Both are number matching in the series. Both come with a 1oz silver coin. Zeus has genuine yellow diamond front sight.  Posideon has a genuine blue diamond front sight. Both are chambered in 45. Collector guns you probably won't see much in the wild. Selling or trading as a package won't seperate. Will send more pictures upon request. Really great detailed pieces.
