The Schwinn fillet-brazed models, Superior, Super Sport and Sports Tourer, used fillet-brazed frames with internal reunforcing sleeves at the joints. I have one of each. These frames are nicely made and virtually bombproof, but the construction reflects Schwinn's obsession with strength and durability before light weight, so the complete bikes range from maybe 29 to 33 lbs.
