I see some guides here on this forum, but none have pictures, How Boring, they suggest buying books? My local Library has those books. Just look online you may come across what you need to find out. Here are some rare pics of a Florence Porcelain with an Original Sessions Clock with patent numbers dating form 1934-1936 respectivley. This one even has the artist initials and a design model number, possibly German made with the Florence Ceramic stamp. i am currently researching this one, so come back for the answer. Thanks
