This is another uncommon tool in very fine condition.
The Stanley 39 1/2 with the brass top, from the Sweetheart era, in this condition, is quite rare.
This one is 6” long and the bubble is in terrific working order. The brass and steel have a nice patina and have not been over cleaned. A great small level valuable to the woodworker as much as a machinist. I use this size for levelling small shelves and drawers, jointer blade set up, and can easily be placed on a longer straight edge to expand its capabilities to almost limitless. A fine and extremely accurate tool.
