Antique Wm Park smooth face iron; Park name on shaft; vintage golf history

This is an early smooth face iron by Wm Park.  It appears to be from the late 1880s or early 1890s.  The Park family from Musselburgh won seven Open Championships over three decades.  The face of the blade is 4" across.  The top of the blade has a nice 'squared' angle to the hosel.  The hosel is quite thick as is the hosel knicking.  The entire oval PARK name stamp is very bold.  The Wm PARK name is also very visible on the shaft just below the grip.  The head has been re set and is tight to the hosel.  The grip is a period type russet wrap.  The club is 39 1/2" long to the heel of the blade.  It has a loft of 25* and has a swing weight of just over F-2.
