Since it is a bit slow this afternoon, I will post a recent acquisition, a ST adamantine called the Arno. Tran shows it twice, from the 1900 and 1904 catalogues. Mine is marked "2091" on the bottom, or 1902. There are the remains of a letter but I can't make it out. This one has features from both the 1900 (dial) and 1904 catalogue pictures (columns, cup bell for half-hour strike). A similar clock is shown from the 1904 catalogue, the Adele. The Adele is a somewhat shorter model, by 1/2 inch. The Arno has an 89 series movement.
