Hello guys. I have a mate who wants to sell me this old surf board. It about 6ft 6in long, with no designer name or inscriptions on it. It has a few minor dings up towards the nose (its still dirty from hanging in a dusty garage for 30 years). It was bought 2nd hand in the early 80s & never used since then. He wants $300 for it. Can anyone tell me if its worth that ?
