| Description: |  | This design by prolific Stanley patent man Frederick Traut (father of even more prolific patent name Justus Traut) features an unusual "drop-in" level/inclinometer mechanism that allows the bubble to be accurately set at any angle between 0 and 90 degrees.
Levels featuring this design were produced by the Stanley Rule and Level company as their #32. |  |
