| Machine story: | 2012-10-18 One digit of the machine was not operating on arrival. Cleaning of old oil residue and internals and case cleaned. Manual movements of all the digits kept them in perfect working condition again. It is easy to see that the design is made for electro motor driving as well as a more digits keyboard. Beside this, the relatively simple design is remarkable. When you compare it with the early adding machines in this class 9 and for instance Continental machines. |
