"Manufactured for Columbus Cycle and Sporting Goods Co. Columbus Ohio USA" There's some nice DX Schwinns in this thread, and one project I have with the exact same head badge.
Sorry, I have to keep the bicycle complete.:) Yah , just a joke

American Standard was a brand name owned by Columbus Cycle. It was common for Schwinn to build bikes with retailer's badges before they got their own authorized dealer network established. There were also other names used by Schwinn that they owned, but by the mid-'50's most other badges were dropped.
