Anyone have any old K & E (maybe Gurley) catalogs? USN training manuals? An old K&E magazine ("The Compass") from the 1890s has this picture of an artificial horizon kit. The "future article" mentioned on the page simply explains the principle of the device and a little about its use. I'm sure it has nothing you don't already know. http://books.google.com/books?id=tX0SAAAAYAAJ&dq=editions%3AHARVARDHXHJ8E&jtp=3 Stanley (the famous instrument maker) describes the artificial horizon in some detail in his book. However, the kit sounds different from yours. The hole in the pan has no screw thread, or at least he doesn't mention it. http://books.google.com/books?id=QzM7AAAAMAAJ&pg=PA405 Nevertheless, the book has a lot of interesting insights from a master craftsman.
