Stargazer's comment make me look further and here is what I found in Aerofiles. I think it fits the bill....
George D White, 117 E 49 St, Los Angeles CA.
White Trans-Pacific Flyer Side-view (1919 Aerial Age) [The side few is no longer accessible in Aerofiles]
Trans-Pacific Flyer 1919 - 3pOmwMF; two 180hp and one 300hp Hisso; span: 82'0" length: 39'0" load (est): 4200# v (est): 100. Laminated plywood construction; truss-braced wings, twin pontoons; side-by-side cockpit in front, plus a single cockpit well aft, probably carrying someone more for c/g reasons than anything else. A most ambitious project that never came to pass, despite announced prestigious support from Pacific Aero Club and Aerial League of Canada, even his honor, the Governor of Alaska.
