I think maybe we are reading "too much" into what is written by an Advertising Department person that never picked up a torch in their life. There's no difference in Torch Brazed, or Brazed Lug. It was just a heat source, A FIRE, that brought the metal up to a temperature that melted a small brass slug that was imbedded into the tube under the Uni-Lug. If you were to section a frame in half you would find a small square dent in the frame tube. In this dent, was placed a small brass slug and it stuck to the tube. Then the tube and the lug were placed into a frame fixture, the entire head was heated at one time with like six torches to the temperature that allowed the brass to flow between the tubes and the lug. This is what was referred to as Torch Brazed, or Brazed Lug. It was not a frame builder, with Hilda hand brazing each joint one at a time, like was done on a Paramount/Waterford frame.
The Uni-Lug frame design produced a quality frame set for a low to mid-price point model. We never had any serious frame problems with this Uni-Lug design. The biggest problem in Greenville built bikes was in wheel building.
