Arnold Palmer Trouble Wood???

Hi all - I just started into golf. Like JUST started. Haven't even played yet, just learning to hit the ball. Friends have been giving me their old clubs, and I am putting together a pretty good set. One of the clubs that I just got is an Arnold Palmer Personal Trouble Wood. I've never seen another club like it, with a slightly V'ed sole.

Anyone know the history of this club. My online searches haven't dug anything up apart from a couple auctions for them.

Thanks!
