This is my first post on WatchuSeek. I bought a large group of pocket watches from an Estate and I have had a fairly easy time researching them. However, this one is really throwing me for a loop!
The movement is marked "Wm J Collison London" with a serial number 12316.
The case back is marked JFN, 11307, and has a lion, crown, and what looks like to be the bust of a woman.
Any information as to its age, maker, or value would be a huge help to me. I attached some photos and I'm hoping someone knows about Wm J Collison.
