The previous version showed 23018 at tip and 23012 at root; unless they were trying to build a freak craft that would not be correct. I am assuming a mistake, and am switching them around. If I'm in error (does anyone have a reliable source?), I apologize in advance.--Raymondwinn (talk) 08:42, 16 November 2010 (UTC)[reply]
