A little board history needed - Dick Brewer

A little while back I came across this Dick Brewer from a friend of mine.  I’ have some descent history on his boards ranging from back when he was making longboards for Bing and Hobie but I’ve never seen anything similar to this shape.  There are no dims but it’s about 5’10 and a good 3" + throughout the board.  Also judging by the plugs up top and the fact that there is very little rocker in the board I am assuming it is more of a kneeboard more than anthing else.  

However, since this is out of my range of knowledge I was hoping that possibly anyone here may be able to offer any history behind this board.  I’ve attached two quick shots but if anyone wants a few more I can post them later today.

Thanks in advance,

Dan

No question it’s a kneeboard. The outline, fat rails, wings, etc …say it’s from the mid or late 70s.
