1875 · Wiberg Machine · Werk 499 von 1.871

A compact difference engine of 1875 the size of a sewing machine, its mechanism folded into a small iron frame, rows of brass figure wheels packed close together, a hand crank at the side, a small printing wheel at the front, the whole mounted on a plain wooden baseboard, the brass warm against the grey iron, the machine standing on a plain grey plinth before a flat grey background, even flat light from directly in front.
Jeder Verweis nennt seine Art. „Vorläufer“ allein wäre eine Behauptung.
