Antique/ vintage Stanley No.113 Sweetheart era compass plane for restoration

Antique/ vintage Stanley No.113 Sweetheart era compass plane for restoration. This old hand plane dates to between 1920 and 1935 - the blade is marked with the SW in heart logo and made in USA. It is a 25cm long metal plane with an adjustable flexible sole. The plane is used for planing timber which has a curve such as the edge of a round table. The flexible sole can be adjusted to form a convex sole or a concave sole, set to the required curvature. The flexible sole is anchored with the frame at either end of the sole with the frame meeting the sole at the center. The sole is adjusted by turning the knurled sole adjustment wheel nut; located on the top of the plane towards the front. The plane will need restoration - adjustment knob is stuck, and plane has some pitting. Great buy for the carpenter.
