The first was Dad's, I do know it was a TTO and adjustable. I do believe that it was either a Slim or a Fatboy. I do remember that he had those two as well as a couple of injectors, one of which was a Techmatic. That would have been in probably the mid 80's, I looked like I lost the fight with Freddie Kruger. Upon re-discovering these, my first purchase was a black tip SS from B&B, although I do not remember from whom. And that was the beginning of my downfall!
