This is a Stanley Bailey #4 Smoothing plane. It is 9 1/4 inches long and is 2 3/8 inches wide on base. The plane is marked Made in USA and Bailey No. 4. Someone ground their initials MPL into the metal side of the plane. I did not take the plane apart and am leaving it up to someone who knows how to do proper restoration. Plane shows wear, rust, pitting, paint loss. These old Stanley planes are known for their durability.
