Does it look like this? obviously the face and key are different but the inscriptions are hard t see from your pics...... if so, rub ya hands together....
Exactly the same case and the movement looks exactly the same, but it doesn't have the same inscriptions as far as I can remember. How much did you get for yours?
Think the watch on its own is still a good couple hundred notes to a collector, but it pretty hard trying to find history on 'Patent Lever' manufacturers.
