- If you are up on the Waltham Watch Company history, you know founder Aaron Dennison immigrated to England in 1868, and eventually started the Dennison Watch Case Company at the age of 62 in 1874.
- Most of Dennison's output went to the London Office of the American Watch Company.
- However, as is believed, Royal Robbins would not let Dennison use his hallmarks on cases housing AWCo movements. So, he used the hallmarks of the manager of the London Office.
- Very likely Dennison used this FFS hallmark (see slide) on his early cases by Frederick Francis Seeland, assistant manager of AWCo office in London. This case houses Crescent Park 816849 (June 1875).
- Later movements, typically nameless Home grade, use Alford Bedford's hallmark on their cases.
