Okay guys, I did a search here and on google and can't find any information on the brand Sun Surfboards. I recently acquired a 70s single fin fish with the label Sun Surfboards. There is a signature but it's written terribly. I think it says Matt Hamil, Mark Hamil, Mark Harris, etc. No serial numbers but it does have the dimensions: 6'6"x30. I'll upload pics soon. This is from the east coast US. Any info?
