Nice little chariot plane which measures 3 3/8" x 1 1/2" mouth around 1/16"
1 5/16" width plane iron which is stamped MB Moulson Brothers - Cast Steel
No maker name on the plane.
The usual rust staining on the sides, the mouth does have what looks like a couple of scratches on either side, as far as i can tell these look like part of the construction of the sides and are not cracks, just where the sides meet the sole.
May need a sharpen, though does have an edge to it as it is.
