So this was a very interesting find. The board would have been made around 1971 - in between the time Pete was shaping at Bilbo around 1970-1 , and later starting Ocean Magic around '73. So it looks like Pete went back to New Zealand for a while, shaped some boards for Atlas Woods (an offshoot of Gordon Woods in Australia) and then returned to the UK. Either this was his personal board he brought back with him / or it was part of a batch of boards he made with Atlas Woods logos which ended up for sale at the London Surf Centre around 1971 (see ad below).
The board is a classic s deck of the time, 6ft 6 x 20 inches wide , with large adjustable Aussie made fin and box.
