This driver is an early bulger style marked “McEwan” on the crown and “McEwan” on the shaft. This compact head has a face that is convex from heel to toe and is termed a “bulger.”  This is the polar opposite of long nose clubs with their inward curving faces.  

Bulgers were developed and introduced by Henry Lamb beginning in 1888. His design quickly took over the golf world and rendered long nose clubs obsolete.  (TCA2 V1 p108).  This club has a splice neck and its original 42 1/2" shaft and sheepskin grip.  A fine, early example of this historic innovation.
