Here we have a relatively early Stanley acorn plane possibly from the 1940s/50s. These were made by STANLEY in SHEFFIELD and sold as their secondary line. Just the same body as their 41/2 but with a different frog. In practice the plane works just as well as their normal line, Good clean flat sole which is the starting point for ANY plane regardless of of price, a ground and sharpened iron the plane takes a long clean shaving see photos, Condition as per photos.
