At a recent estate sale, I found this Stanley No. 4 ribbed plate plane. It was a throw-in item to induce me to buy two tool boxes I didn't need. It appears to be a Type 11 manufactured between 1911 and 1918. The blade has the Sweet Heart logo which is a little confusing since it is from a later time. It is missing the lever cap, but the rest of the plane is in good shape with no cracks. It does need a major cleaning. More to come on this tool.
