OK I now have the full story for you
in 1973 Ray Turner the First Cranmog Centre Secretary who wrote one of the first miscellany reports decided to design a club badge
The badge was entitled "scalded cat"
The Early prototype was renowned for the paint peeling off and the president of the club used to employ his grandson at weekends to repaint the peeled areas for extra pocket money
the badge then evolved into the ceramic types that we have today
The badge you showed is one of these early prototypes and very rare indeed!
Cranmog will be launching their 40th Anniverary badge very shortly so another evolution of the logo
