Back in the 70's, Astronomy or Sky & Telescope magazine advirtised a "wind up" camera clock drive that I believe was German built and used to track stars, planets, etc. It was supposibly pretty acturate and wasn't that expensive (I bought one but, have long forgot what happened to it). Does anyone remember the name of it or if they still make them? Is there anywhere on the internet that has a picture of this?

That is so 1970s of you. They have accurate electronically controlled, battery powered drives now that are quite cheap.

My grandfather had one in the 70's, 1870 to be precise, but why would you want such an antique trinket, it seems a bit peculiar to me.
Its a tall order for a clockwork toy to be "pretty accurate" AND "capable of tracking stars AND planets etc" and "used for astrophotography". I'm sure the Chinese made one, and threw in an abacus for good measure, which was also pretty accurate.
