What is the history of dunlop max power golf clubs?

They were developed in the 1960's in the Slazenger factory at Horbury Junction nr. Wakefield. The Manager was called John Reid although the clubs were the idea of one of the employees, a single figure handicapper.

The set of irons had individual steel shafts which had a different kick point depending on the iron number. The lower the number, the higher up the shaft was the kick point (created by the stepped shaft diameter reductions). The principle, of ensuring that all the clubs swung with the same characteristics and feel, was brilliantly successful but expensive to manufacture.
