專家說明

Based on the design of Thomas de Colmar, Arthur Burkhardt issued his clones of the Arithmometer in the 1870s when "the machine deemed sufficiently successful to be worth copying" (Johnston, 1997). The quality of the working mechanism is still evident, and when first issued the machines would have been well treasured and certainly worth the price of $241.50 as advertised by Keuffel & Esser, in their Catalogue of 1899.
