This machine appears to be a prototype of this proposed mechanism, and here the crank has been placed in front! Achieving this was certainly not a job for amateurs. In the prototype the new mechanism set up is perfectly performed and it seems highly likely this amendment was done by workshops Bunzel. All the pieces seem original, coming from the same time (even the wear). The arithmometer also has been provided with an ingenious tilt system which ensures that when the machine is inclined, the crank is perfectly horizontal.

ca 1913 Bunzel-Denton Arithmometer Prototype
Rare arithmometer Bunzel 7, model baby - carriage with 7 sliders and dual display. Almost certainly the only known copy and probably a prototype with a shifted crank created by Bunzel. Serial 8080 dimensions 23 x 32 x7 cm Weight 9.5 kg
