Here another one, also bought today, the same seller like the Brockbank & Atkins clock (thanks to Nathan again for the photo permission). I should think about keeping away from UK selling sites, so many great clocks and watches around there
I know nothing (other than that is is special) and have no idea how to date it. The dial is enamel and nearly mint. Any information and thought is very welcome!
One thought from my end: At the lower right side of the backplate there is a thread and two holes without anything attached. I believe that originally there was a foot of a bracket attached, to which the pendulum could be fixed for transport. Any other idea?
