There's something very clean about these early Schwinn lightweights, this 1941 New World being a good example. It's hand brazed, but without lugs.
The bike also has a minimum of accessories: a fenders, a bag, and a bell. You could add a modern LED if you needed to see in the evening or morning. Period electrical components aren't as good.
People see a Schwinn and assume it has a single piece crank. This one has a neat three-piece Schwinn crank system based on Birmingham England designs like Hercules.
