Originally 15 Ding-A-Ling Robots were produced, each designed with unique functions and personalities. These were Shoeshine, Gofer, Spy, Brain, Answerman, Driver, Chef, Claw, Constructo, Fireman, Rocky, Flying Saucer (Twirly), Bank, Policeman, and Boxer. All models were apparently included in various play sets in different combinations but most were available as individual purchases as were their power packs. Some were rarer than others. Boxer seems to have been the most common while Banker, Policeman and Spy are rumored to have only been released in Europe. Other designs were proposed such as Cowboy and Jack-in-the-Box but to date only one example of each has surface. The Ding-A-Lings on this site are ones I have personally owned or verified by other collectors.
