I also had the same movement, FHS. I don't know the number. I took the movement out for cleaning and I took a closer look at the writings at the back of it. I saw "FHS" in it.
Some grandfather clocks have keyholes. They are large pulley driven weights that you wind. My Dad made a clock with a pulley driven movement in the 90"s
It can get pretty confusing to distinguish the movement of an especially older clock by both appearance and chimes. Jauch clocks have a distinguishing chime key which modern-day Kieninger single chime ones also have (Westminster quarters in C major and the hour strike chord being some type of E flat chord). Even older Kieninger clocks from before the 1980s had “Urgos-like” chimes. This particular chime is often associated with Urgos though.
