Recently acquired a crystal regulator, JUF, it took some cleaning and one tooth straightening on the escape wheel and now seems to be running well. However, because I had to remove the movement, I noticed a couple of things that make me question if it is totally original. When I removed the movement, I found "Anniversary" on the face, but not on the movement, itself. Horolovar Guide says that Bowler and Burdick had all the anniversary trademark clocks marked with "Anniversary Trade Mark Registered." The question arises because I have another similar one that has the "Anniversary Trade Mark Registered" on the back plate, as well as on the face. That one has a round movement, whereas this one has plate 1471. Everything is JUF. The "Anniversary . . ." is actually covered on the face because of the more ornate surround on the "new" one. So, the two problems are that it is not stamped on the backplate and is actually covered up on the face by the surround. I have a feeling the face was replaced. Any thoughts? It is probably not as severe a problem, because I know that JUF movements are in these type of cases, but it would be nicer if all was original.
