The crown of this putter is faintly stamped "Burke Endgrain E3."  The wood used to make Burke's endgrain putters was oriented so the endgrain formed the face and would give the golfer a solid feel at impact.

According to Burke's 1917 catalog, this EnbgrainE-3 Hammer Head Putter had all the benefits of their other end grain putter only it had a "fiber direction mark" and was weighted "so that the putter in the stroke hangs perfectly true."  The lead buttons on the heel and toe might give this club the appearance of being heel-and-toe weighted, but it's not.  Instead the lead runs through the entire length of the head. 

The 35" shaft and leather wrap grip are original.  For more information on Burke endgrain putters, see TCA2 v2 p433-434.
