After years of searching, I finally found a lackscilduhr mit surrerwerk. These clocks are around, but not in the USA so much, and not easy to find a German seller that would ship one to the USA. Anyway.....this looks like a good example...looks complete, but dirty. The dial looks alright, but a little deteriorated. I immediately wanted to preserve the dial. So, I applied a couple coats of Renaissance wax. I had to be careful with the spandrel decals...they already had a little loss from mold and mildew. The wax took an ever so slight bit more off the spandrels, but nothing significant. The remainder of the dial suffered no loss from the wax. Now, the dial can be handled without as much caution, because it's protected. But, using the wax caused an unexpected result. The dial is bowed. And the clock came with it's side doors. When I received the clock, the doors when installed would not swing all the way out, hitting the bowed sides of the dial. After I waxed the dial, the doors can swing all the way out without hitting the sides of the dial. Neat! The clock didn't come with weights or pendulum. If anyone can tell me the specs of surrerwerk weights and pendulum length, that would be appreciated. Perhaps I will feature this clock in it's own post later, when I have more time.
