Glen I don't have a copy of the Summit mold book thats out there, however an advanced WG collector I know informed me that it was believed it was leased to Summit by a private collector who has approx 500 WG molds. The private collector was friends with the Fenton family & they (Fenton) stored the WG molds for years & now that Fenton is closed supposedly they may be on the block in the future, but they are not included in the 5/24/12 auction which has 10,679 molds on the block. I was told Plum was using some of these these molds for a few years making stuff for Rosso. I assume that if this was a leased mold Russ was using it was returned after his unfortunate passing. NCC bought most of Russ's Cambridge molds & I think on the QT something was worked out for the few Cambridge molds Fenton had. Anyway thats what I was told. Ken
