I was going through some boxes of old engineering reference materials and came upon a booklet by Handy & Harman titled, "The Brazing Book." In the Brazing in Action section there was a case study for Assenmacher Lightweight Cycles.

There is a more modern interactive version of this book on line at www.brazingbook.com
