ETA: Found a digital copy of Comic Cavalcade #14, which details the consequences of an Amazon-trained woman removing her bracelets. It's quite an interesting story, but very different from later interpretations of how the bracelets work.
I think going over various depictions of the bracelets could be quite an interesting research project, but not for me right now.
