I live for the CABE
The oldest crank date on the registry is an AS 15No insight on whether Schwinn was building for Shapleigh Hardware/Rugby badge. That frame with Rugby badge was a frame sold by a Caber and had the fork missing unfortunately. For the most part, when I see a potentially pieced together bikes it's tough to know as so many are so well done. Of course, more examples that are less "complete" or "as found" need to emerge to gain more confidence. What is the oldest AS crank year stamp known? Maybe start there? But yea, the 20's were rocking it with so many players, bankruptcies and "mergers" as we know playing into the depression era.
