Cran Cleeks were made for a fair number of years, though not in great number.  This Wright and Ditson example is about the earliest you will find.  The inlaid wood insert extends well forward of the rest of the iron face. On typical Cran irons, the front of the inlaid insert is flush with the border of the face.  The back of the head is marked "Wright & Ditson" and nothing else.

Because this iron does not include James Cran's 1897 patent information or even the words "Pat Applied for," and because the insert extends well forward of the rest of the head, I believe this iron was one of the earliest Cran cleeks ever made. The shaft and grip are original, as is the wood insert which has a small and relatively insignificant crack low on the heel.  An outstanding example.
