A special version was produced for Germany with the same project number and project release date. The schematic part number for the US version is W-1042-85d. The German version is W-1042-86d. On both schematics, the game name is shown with a hyphen, as "See-Saw". The whitewood prototype pictured in this listing has a one-player head, no backglass, and works. A few subtle playfield changes were made on the production version. The cabinet has the artwork from Bally's 1968 'MiniZag' but has no serial number. Additional information is included with some images. We previously showed a manufacture date of September 1970 for this game.
