Mortgage Lifter. A variety of indeterminate heirloom tomato developed in 1930s by MC Byles, "Radiator Charlie". His nickname derives from the radiator repair shop he opened at the foot of a steep hill as overheated trucks invariably found their way to him. The huge beefsteak tomato he developed proved so popular that he paid off his mortgage within six years, charging a dollar apiece. These pinkish-red fruits, weighing from 225-5500g (8 oz - 3 lb) have great flavour, meat flesh and few seeds, appear late in the season.
