Speed Fins? Jim Banks Fins?

Im attempting to find a set of whatever fins fits this old LSD boards boxes. If any one recognizes what they are that would be great. Anyone who has fins that fit that would be even better! 

I would try JP @SurfySurfy. He’s on IG.

John over at The Board Source in SD has hooked me up with some weird fins before, but he’s not super keen on selling his stock of hard to find fins, so you have to ask real nice and maybe buy a board.
