This is an old innova putter. I'm guessing it's an aviar from the fact that it looks almost identical to my aviar putt n approach. The only identifying marks on the disc are:

PATENT NO. 4,568,297

INNOVA CHAMPION DISCS, INC
SAN MARINO, CA. 91108-8368

And a black stamp that may have said something at some point.

The putter was given to me by a local pro around 1998. I used it for everything until I got a driver(polaris ls) then it became my putter until about 3 months ago when I got a wizard.

Here's the pic:

Looks like an aviar putt and approach with a H.O.T. (Heart of Texas) hot stamp.
