content: This model of an adding machine section has a single black key “1” key, with a complementary 0 digit, in the rightmost column. Left of this is a column of nine white keys. Keys for odd digit keys are concave, and those for even digits are flat. Three numeral wheels are at the front. The rightmost has alternate zeros and ones, and the two to the left both have the digits from 0 to 9. There is a handle on the right side. There is no case. The keys apparently could be used to add shillings (there being 20 to a pound).
