Measurements: left case – 46.3mm in diameter; right case – 46.4mm in diameter. Both are stamped HOLY FRS on the back case and X DEPOSE R?? On the inner rear case. The inner rear diameter on both cases where the movement goes in measures approx. 25.4mm and the dial side opening measures approx. The left case has a nice dog and duck hunting scene while the right case has a deer family scene. I’m not sure if these are sterling or coin silver but both have tarnish which is typical of silver as it ages. You don’t see these cases for sale too often.
