I recieved a old pocket watch that belonged to my grandfather that is marked 'JMF Co.'. I have assertained that this came from a company that produced jewelry in Attleboro MA probably shortly after the turn of the 20th century. I find that John Melatiah Fisher was an influential man in and around Attleboro during this period. I can find nothing more on this time piece though as to whether this was manufactured by J.M Fisher Co. or by someone else and marketed by them. I find near to nothing about this company or these watches. Can someone tell me something about this watch? Thank You!
