| The reassembled and working machine. The red cap on the top- left "Error" level is missing; the three red keys on the right are "Total", "Subtotal" and "Non Add" (there is no subtraction key!).The calculator had one broken spring and a couple of blocked levers and wheels, due to the extreme rusty state. In this restauration, not all rust has been removed, to maintain an impression of the fate of this calculator: age and neglect! | |
