OK, i just picked up an nice 9" chunk today, but i have no idea who makes this Posi unit and neither did anyone esle that saw it.
I did find these #'s ( A6 15 24 ) on the side which you'll kinda see in one of the pics.
It's suppose to be a Moser Enginnering built chunk. The only thing i found close is there new WaveTrac unit, but i think it's only a 35 spline unit? And the big end is different.
Let me know what you think. Any info will help.
