A Dunlap 3Dbb Smoothing plane. This is essentially a copy of the Stanley Bailey #4 smoother.
In great shape for a vintage plane with rust stains, but no pitting. See photos for details.
The blade has been flattened and sharpened to a 20° bevel. This should be ready to go out of the box with possibly minor fettling required. A great worker far a fraction of the price of an identical Stanley in this condition.
