A third generation Dynamobil with fall hammer. The accessory underwent no mechanical changes for the third generations, but had it’s graphics slightly altered.
A third generation Dynamobil with three accessories; polisher / tumbler with new color scheme, twin drop hammer, and newly designed twin trip hammers. I have seen very few of the third generation pieces and suspect that Hess closed it’s doors soon after manufacturing began.
A small size third generation Dynamobil on tinplate base with trip hammer.
A first generation Dynamobil with a very large trip hammer. This trip hammer was spring loaded and the tension could be adjusted, resulting in a louder, more forceful blow.
