Got this board at a garage sale: Dimensions: Length: 8.0, Width: 19.5 Nose: 12.75 Tail: 9.0 Thickness: 2 7/8 Moderately rounded deck, pretty flat bottom, minimal rocker with kick at the nose, 60/40 rails, single box, no plug. “Rayo de Calif” logo on deck, “Clark 409” (# and name written in pencil on opposite sides of stringer at tail), no plug. Very, very good condition. Anybody: What’s up with this kinda Lopez-lookin gun? I have no clue. 70’s? Help please. Thanks.
