We note that the manufacturer's flyer, which is for distributors to read in hopes of encouraging sales to them, states a single ball "down the middle" can double or triple the score. Presumably, they mean that a ball ejected from the top kick-out hole and going SDTM could hit all eight rollover buttons. In contrast, the manufacturer's advice to the operator, shown in our Files Section, specifically advises operators how to prevent that. Production start date: 12/08/50 Production end date: 02/28/51 We previously showed a date for this game of January 1951.
