I know very little about this board, it states John Hall designs who was an Australian living in North Devon in the 70’s but these are only stickers alongside the fins. It looks like the fins had some kind of branding on them at some point. The channels look sprayed but they are actual channels which I think is quite unusual for this type of construction. It’s hard to get a photo of these. Not sure who Andy is (sprayed on the top) A few knocks and scraps but nothing crazy. Great Wall hanger if anything else Collection from tavistock, Devon
