This is an old vintage Stanley Rule and Level Company level made sometime probably around the turn of the century in New Britain, Connecticut. There are patent dates on this level of 6-2-91, 6-23-96 and Mar 25, 90. This level is in overall good shape. The only issue is that it is missing one of the circle insert leveling vials as you can see in the photo. The other two parts of the leveling vials are intact and in working condition.
