• Mr. Marcello Nizzoli for the body-case design.
• Mr. Natale Capellaro (several pattens) for the mechanisms

The machine was from the sale on family-owned and was still in use by the sellers grandmother, in the 80s, for several invoices in their reputable wine business.

First observation showed ride away a very clean and well preserved inner machine. It looks like if it had excellent maintenance last week. (The machine was from the first selling on, family-owned. Please see at: Previous owner)
It was sent in a perfect wooden reinforced box, well protected against transportation / shock. One of the best I have ever received, thanks!!
Nevertheless the machine keyboard was shifted eight positions during transport and the GT key was shifted to the left, resulting in a blocked machine in the rest position of the main shaft. In this position the motor was not activated. Manual turning of the main shaft was not possible. Try to see if the keyboard pin-box was blocked or so. This by moving it manually from the bottom side of the machine. This gave, after a few tries, the keyboard free for inputting. I pressed the adding key to see if the machine was coming to a reset. That works as expected and the pin box was shifted back to the first digit position.
Multiplication was not coming to an end / stays in an endless loop. Turn the mains haft manually and turned it a little back and forth at the rest position releases the "=" key, and ends the loop.
Adding was not generate an carrier, like earlier machine two. Oiling the mechanisms here will need some time to let the penetrating oil to creep.
After a few hours the first try was giving a correct result, including the expected carry!! Then a few more complex addings, multiplications and divisions where carried out with correct results, please see the list pictures. A short restoration! and an other nice machine functioning again. Thanks the good storage / maintenance and use by the previous owners and a little oil here and there.

I print a date left of the calculations. I updated it manually. I got input of Mr. D. Schwabe that this is the only way. Divisumma 26 has updating possibilities via the key board.
Made a picture with the acoustic noise reduction ground cover.
I just got the function description of the GT key, again from Mr. D. Schwabe and I discover that the 4th and 7th digit does not work properly.
For those who like to know the function:

Every result of the calculations ended with the * key (total sum), is added to a Grand Total register. Fi 2x3 + 3x4 + 5x6 can be show the result by shifting the GT key to the left and push the * key. The shifter most right should stand at the green dot.
