I have a set of PSH Large Quads and want to know where to get replacement fins.

I know that the rear fins a rear controllers (not hard to tell given the shape).
I understand that the standard front PSH fins are Pancho Sullivan fins (120mm deep and 119mm base).
So what about the PSH large fronts? These fins are about 125mm deep and 130mm base.

It seems there are standard fins that get re-branded and mixed'n'matched to come up with different sets. Anyone got an idea what these Large front fins are called now?
