What at first glance appears to be an unprepossessing silver golf pencil, turns out, with a pull on the end, to be a magic pencil -- and one made by the fabled firm of George W. Heath & Co.
It's no accident that its styling recalls the streamlined golf pencils of the 1920s and '30s, for this is a very late magic pencil. The design, with the screw-off lead reservoir shown below, was the subject of US patent 1,514,965 -- the very last of Heath's writing equipment patents. The application was submitted on July 19, 1922 and the patent was issued on November 11, 1924. The "PAT. APP. FOR" imprint locates the pencil between those two dates.
