I'might assuming that picture wasn't taken by you or else I'd just tell you to turn the club over and look at the back
I did a quick Google search and found Tzoid Pros and Tour Classics both had Mizuno stamped on the sole, but neither look quite like these clubs (the numbers don't look the same).
At a charity scramble, there was a putting contest where every entrant had a chance. It's one of those things where the putt isn't quite straight, but it's 30 feet or so, is setup with rocks you have to avoid (not in the proper line though) and foliage arches, etc... Well, I won the whole thing (qualifier round and final round), and the prize was a Cleveland 56 wedge. [I assume there are charity scrambles which run chipping contests too, where the prize is a putter! lol]
My associate club has a raffle at the end-of-year event and in the last 2 years I have won $150 and $100 gifts card for nice area courses. I am expecting a box of Rock-flites this year, though.
