That is very true, but not all of them, at the moment most people with watches with Massey escapements should try to find out when they were made, and where. Edward Massey was only at Prescot for 6 or 7 years, and it is in that period the EIM was used, though never say never.I remember reading that watches with Massey's escapement that were made by the firm had EIM stamped or scratched in various places, like under the balance cock.
I only know of one example of EIM - listed in Treherne's catalogue p.23 EIM IP from an uncased Massey I movement, and described as 'probably standing for Edward James Massey Improved Patent' - Edward James Massey being the Edward Massey's eldest son. There is also FM P on Francis J Massey's #431 pump wind Massey III from much later ~1840sI remember reading that watches with Massey's escapement that were made by the firm had EIM stamped or scratched in various places, like under the balance cock.
I know you are a busy man Peter, how about a nice quiet Sunday afternoon?I come back with additional photos as soon I am back from my holiday.
