I have what is called original frisbee disc. It's a putter. 171 grams. Made in Mexico in 2003 by Whamo Inc. It's got these ridges on the top where you would put your thumb during a putt. Really stiff. Never seen another like it. Found at the bottom of the hill on hole 5 down under. No name or number. I think someone might have chucked it down there on purpose.
