This is a 9'6'' x 22" Shane Russell Hughes Excellor, shaped by none other than Dick Van Straalen, C. 1966.
While clearly a "longboard," it features a George Greenough style fin and a seriously rolled bottom...not unlike Nat Young's "Magic Sam."
Russell Hughes was one of the first Australian surfers to embrace the refinements inspired by Greenough...and yet, he continued riding longer boards when "everyone else" had dropped down well below 9 feet.
Hughes was still on a longboard in The Hot Generation.
Greenough's epic tube riding center spread in Surfer Magazine -- which kick started the new era in terms of the media -- featured Hughes on a longer board at Noosa.
By winter of 1968, Russell acquiesced to the times, and began riding shorter boards...
He went on to a very respectable 3rd place in the December, 1968 Puerto Rico World Contest -- ahead of Nat Young, Mike Doyle and Reno Abellira -- on a shortboard. Young later said he should have won the event. (Note the double stringer on the shortboards above and below...like his Excellor model.)
