I was pondering this last night when looking at an anonymous longcase and trying to think about where it was made. Why were London makers of longcase slower to adopt rack striking than provincial ones? It clearly happened, but why? Was it customer resistance? English clock and watch customers were notoriously conservative but London was where all the fashions started. We date clocks fairly precisely based on London fashions knowing that the further away we get the less reliable that gets, but when it comes to striking mechanism that appears to go in reverse. I have a Dorset longcase from around 1700 with internal rack, had it been London I'm sure it would have been internal countwheel. Like all things clock related there are no hard and fast rules, I saw a Dorset 8 day longcase last year made after 1750 with external countwheel, even in London they had stopped doing that 40 years or so earlier. I just don't really understand why in this aspect London wasn't leading the way.
