What do the numbers on the bottom of Pyrex bowls mean?

In many but not all cases, the trailing digit of the model number corresponds to the capacity in pints of the bowl or dish, e.g. #043 = 1½ quarts = 3 pints. Sets were typically assigned catalog numbers similar to the model number sequence of the pieces they contained, e.g. a #470 set contained 1 each 471, 472, and 473.
