I have inherited a 400 day clock, I remember it working as a child.. Can anyone give me some insight, it appears to be a cheapy because the only identification on it says, "Made in Germany", no brand, no numbers, no nothing, anywhere. Was that normal for clocks? It is not in great condition, Missing the glass dome and a couple of balls. The workings are suspended from the top and I cannot find other examples of this. The back plate is 72 x 93mm. I am interested when it was made, why no markings, is it of interest and what it would be identified as. I have included a few pictures. I hope somebody out there in clockland knows what it is, I mean was.
