This is a Waltham 18 size, model 1877, 15 jewel, Waltham Watch Co. grade, adjusted, hunting case movement. The dial is a private label for 'Jas. F. Kingan', 'Staunton, Va.'. The serial number is 2564793. The movement runs, but out of beat. If you look at the photo, you can see that the hairspring is off-center. I have not serviced this one.
