I recently purchased this clock and was hoping for more information. The engraving for Tiffany looks a little odd, I think it says TIFFANY & COMPY? The movement has AF with a circle around it, anyone know if this is the trademark for the actual manufacturer and who it is? Is this French? Under the Tiffany engraving, it says 1913, does this represent the date? On the escapement, are those jewels, what are they made of? What type of clock would this be considered? Thanks for all your help.
