Just noticed that the "Drake II 1G" is now shown among the Drakes on the Toto web site. There's a photo, but no literature yet.
Different tank and trip lever (not as attractive to me as Drake II regular tank).
CST454CUFG and CST454CUFRG Right hand
List price $580; for comparison the Drake II list is $536.
Terry's price in Seattle is $399.99
