Greetings! This is my first post and probably in the wrong place. If so I apologize. I am curious to know if anyone out there knows what serial number Parkinson & Frodsham started with regarding production of their chronometers? The lowest I have found is 133 that was sold on an auction site. I would tend to think they might not start with 1. I have Mercers book but that does not provide much insight regarding my question. Any information will be greatly appreciated.
