Shelton Plane patent 1914609 made by Shelton Plane & Tool Mfg. Co. Shelton Ct. Which is only two towns away from were I live.
It has an odd way of holding and adjusting the iron. The iron and cap are held down with a bar across in front of them as well as a screw into the body of the plane with no frog and adjusted with the screw and lever on the front.
