Dogies

The manufacturer produced the backglasses in both crystal glass and Plexiglas. 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-1042-47a and the German version is W-1042-48a. The early production machines had a green 'Dogies' logo on the backglass instead of the final yellow one. This can be seen in the Flyer. Christian Jacobs, a collector in Germany, told us of a telephone conversation in which artist Jerry Kelley told him that the "Sneaky Joe" name on the playfield was a reference to Joe Dillon (Bally Marketing at the time) put there by Kelley who was unhappy with Dillon about the change of primary color on Bally's 1967 'The Wiggler' from green to purple. We seek your images of examples of this game showing the factory Add-a-Ball conversion kit installed.
