According to an April 11, 1912 "Golfing" advertisment, "The 'Peggy' iron, patent miralite and wood face, drives like a wooden club, made in cleeks, irons, and mid irons... only from J. Turner, Denham, Bucks."

The construction of Turner's insert is quite involved.  The miralite insert, also visible across the top and bottom of the blade, is keyed into the head (the back of the insert is wider than the front). Within the insert are twenty-eight wooden pegs: four columns of five pegs and two columns of four pegs.  Two metal rivets are also found in the face, to help fasten the insert.

The back of this exceedingly rare Peggy driving iron is marked with Winton's diamond cleemark and the words "Driving Iron, Hand Forged, Special."  A most interesting club in nice condition.
