The 'PerWhit' Patent convex Putter c.1926
Club: ‘The PerWhit' Patent no. 247116 Putter
Maker: Hendry & Bishop, Edinburgh, Scotland.
Shaft: Original, straight shaft, with vintage leather grip.
Condition: Very good
Other details: An unusual 'PerWhit' patent half round/convex, punched face putter, made by Hendry & Bishop, Edinburgh. The convex face of the putter was designed to help the golfer to strike the ball with the same face angle regardless of whether the club face was on the 'up' or 'down' trajectory. The curved bottom of the blade also prevented the putter from snagging the ground in either the back or forward movement of the 'putt'.
‘PATENT No.247116’ and the 'Mitre Brand' of Hendry & Bishop stamped on the reverse of the blade.
Albert Frederick John Percival and Ernest Robert Whitcombe received a British patent for the 'Perwhit putter' (No. 247116) dated February 11, 1926.
Hendry and Bishop, Edinburgh and Leith, first produced 'Mitre Brand' clubs in about 1910, however the words were not added to the stamp until 1926.
