Early tri fin

When did shapers use these types of fins? All three fins are adjustable like today’s longboard center/single fin. This is from an older Robert August board.




That's the mini-version of the FU box.

Thanks for the reply. Would adjusting the side fins have much of an impact on the feel of the board?

Assuming the fins were toed in and canted properly, then YES adjusting them forward and back may have significant effects.  But if the toe and cant is all wonky or non existent then fore and aft adjustment won’t fix things much.
