Here's @BFGforme 's 1945 DX. I don't believe the post war lightweights used the same BB shells as the balloon models but I'm thinking they were possibly stamped with a serial # around the same time. When these shells were used to build a frame is unknown, and it seems that the early post war serial # C series was used in multiple years. It looks like that blue New World has the smaller gauge drop out and supposedly the 47's had a thicker heavier gauge drop out.
What's interesting is that Schwinn was making BB shells and stamping them with serial numbers at a rate of 1500 to over 5000 per day in 1948. If we say that they only made 1000 per day at this particular time these two BB shells were produced only 4 days apart.
