Only thing I can extract from the picture is that the engine is a Hatz 85, 89, 780 or 786, to judge from looks of the starting crank gear and sheer size combined. 10, 12, 10 and 12 HP and anywhere from 80 to 100 kilos for the 8* and from 60 to 80(lesser figures if the rare light alloy crankcase is used) for the 7** models.
