Facit calculator

Facit Model C1-13, S/N 556608, 1957. 

New model numbers were allocated in 1957, with the TK-style machines becoming Model C1-13. The mechanism did not change significantly, but the case and clearing levers were re-styled, the numeral keys became square, and the Facit badge became round. This 1957 machine is still finished in the earlier two-tone green, with the Facit name spelled out across the back on a row of separate small round buttons. The metal foil label above the registers was prepared by the local agents as a conversion table from pence to decimals of a pound. A more technical label was available for scientific and engineering applications.
