Several Don Toro Smith?

[Palais]

We have two Don Toro Smith, heavy from Pittsburg, Pa. One fighting between 53-67, the other from 86-89. This can't be the same guy?
Besides, there are 5 other Don Smith's registrated.
Can somebody help out?

Shades of Mamby, Duran. (Maybe Sr.-Jr.) Identified a 70s Middleweight out of Vegas, and Dontel Smith.

Don "Toro"Smith got bombed out by Liston and Frazier. The later version was his son Don Jr.
