Sorry,
I was not thinking when you asked about the QT models, no sega never made this model, they made a console called Ascot and a gunball Blackjack machine,
Most of my connections are with the Las Vegas people, Mickey Wichinsky of Games of Nevada was sent to Las Vegas by the New Jersey people,in 1957 he bought out Jack Lavinia's route in Northern Nevada to operate slot there, he then had a piece of The Sands, it was Mickey who first placed the new Bally Commander-Money Honey in the Sands and the Tropicana, it was in the Tropicana that the machines started paying out for no reason, it was close to the airport and the radar caused many problems in those days, The original Bally Commander was developed from a Bally Draw Bell machine they used the reel mechanism but designed a new handle mechanism that fell to pieces on location after about one week, Doc Kaufman redesigned the cabinet and handle assembly and The Bally 742A model was introduced, this was the first slot machine where Bally used numbers rather than a name on their machines, The name Money Honey was given to Bally by my partner at the time-Cyril Shack, we were the distributor for the U.K. (See the original Money Honey Brochure from my collection),we had the Bally machines before they went back to Vegas, see the attached pictures, the rest is History.
