In March of 1912, Charles Seely received a US Patent that covered the long forked hosel on this mashie.  The purpose of Seely’s iron, as compared to a typical iron during his day, was to take weight away from the hosel and position it across the back of the blade.  Spalding produced these clubs between 1912 and 1919.

 All the stamps on this head are clear and strong, including "Seely Patent, Pat'd May 14, 1912., Spalding Gold Medal."  The 37 1/3" original shaft bears Spalding's Gold Medal stamp. The replacment grip is old and matches up well to the club.
