Duffy’s debuted in the Motion Picture Almanac in the 1955 edition, owner D. Grouenhorst, no capacity number, under “Slaton”. By 1962 the listing had been updated to 250 cars, same owner, corrected city name.

The MPA didn’t make a lot of updates for a while, and when they rebooted their drive-in list for the 1977 edition, Duffy’s was no longer on it.
