grips sizes of 80's wilson graphite sticks


So, I was asking a seller about buying one of his racquets, but the decals had fallen off and the but cap doesn't have the embossed sizes like the later ones. Are there other markings on the racquet to figure out the grip size?

There's half a chance that the bare handle would reveal a single number designating the grip size, either embossed or debossed in the foam.
