This document was created by Chris Perkins (not to be confused with Wizards of the Coast's Christopher Perkins) by pulling together text and images from various other Dungeons & Dragons (and Castles & Crusades) books. The other people credited are the author and artists of the original works, but they did not willingly (or even knowingly) participate in creating this version. The "rip, strip and re-equip" approach means that this RPG item is considered a RPG Sandbox. The quotation marks around the item name are to emphasise the unofficial status of this work.
From Chris Perkins:
UA became [this]... which incorporated and expanded upon all of the material from UA.
