OK let’s hear what the clock experts have to say. It looks to me like an English lever with the characteristic shape of the teeth of the escape wheel and the layout of the escapement. Of course platform escapements are replaced sometimes but this one seems to be right.Hi Stephen, Yes I would say the same, there are indications that clock could have been imported, the compensation balance looks to be Swiss-the clock people on here may know more, not that it really matters, its a first-class carriage clock sold by a top firm. I wish it was mine.
