it is a clock, a very accurate clock, but more of a time calculator when it all is put together, there is a patent on it for a very good reason,
the american patent office hid part of the patent paper work, and the ones listed where the patent originally happened, i couldnt find on line long ago
here is something interesting, it was filed in 40's herein the usa, and it was minus some of the paperwork of the original patent, and now, they changed the date to 1892 or whatever in the usa patent office, which is not true, the usa was not listed on the map…
