Dear Mike, I have a spare blade of the correct vintage and made of solid mahogany. It is thinner than the one that I now use but in good condition (the stock was starting to split so I made a new one and fitted it to a later blade that we had kicking around the club). Let me know if you want it, I am in York and would be happy to let you come and help yourself to it  FOC..Steve Parry Association Secretary
