Zippy sticks by Roger Cooper

One of my most recent finds is this Zippy Sticks diamond tail, from the early 70s with a beautiful eggshell blue/green tint. Shaped by Roger Cooper, it feels like quite an early one it being quite narrow with a ply and resin fin as thick as my finger, and the tail shape looks early. This board had sat in an attic for many years and I think this year is its first out of Wales ! It is 6'10 x 19 3/4 x 2 1/2.
