Shoreline Surfboards single fin

Continuing with my weekly check on whats been on ebay, this caught my eye, a rare singlefin made by the little known Shoreline surfboards of Watergate Bay, Cornwall. I don't know if this make is familiar to anyone out there but its a new one to me. Its 7 ft and the seller dates it to 1968, theres no shapers name and the logo looks hand drawn, interesting board though and it goes to show there's more surfing companies than you think.
