Hi, Hellexarus. Thanks for pointing that out - it seems it was done by an anonymous contributor yesterday. Luckily it wasn't of much harm.

As for the histories - the documentation of a template is typically kept on a subpage, rather than the template itself. In this case, it was Template:Infobox:Weapon/doc.
