Hello, John. That is a fine looking plane!!! I like the corrugated sides, what does the sole look like? I went through a couple of old Sears catalogs, nothing in a Jack Plane with a 4 edge cutter. They offered a cast aluminum body plane with a 4 edge cutter, but it looked more like a Surform. First one I have seen, great score, with the box to boot!!! Regards, Lou
