This snuff box is fully hallmarked for Hubert Thornhill of London. Their address is stamped on the back of the box Thornhill 144 New Bond St. where they moved to in 1875 so the box dates to some time after that. The owners initials K.E.C. are etched underneath the box. The box measures 2" X 1 1/4" X 9/16". In the center is a compass that looks to be in working condition. The hallmarks are under the lid and on the inside of the box. The hinge is tight and the lid closes tightly but there is a very, very tiny gap on the left front side. There is one dent on the left back corner of the lid and a very tiny one on the front left corner.
