Register of Millionaire Calculators

More than 5000 Millionaire calculators are said to have been manufactured by the Egli company in the period from 1895 to 1935.

An early advertising booklet produced by Egli for the American market lists 33 major customers in the USA and Canada, some with 2, 5, or 12 machines.

A similar booklet produced by the Australian agents (Peacock Bros) in about 1908 lists 18 named customers "and numerous others" in government, mining, and commercial concerns. Mr Ray Mackay (formerly service manager of Peacock Bros) estimates that perhaps 50 machines were still in active service in Australia into the 1950s. Many of these are known to have been destroyed or sold for scrap.

This page is a register of Millionaire calculators that are known to still exist in public or private collections in Australia. I would welcome advice of any additions, from within Australia or world-wide.
