Minecraft wiki entry for Unused_textures, associated text: Indev 20100206 also added a duplicate oak planks texture. This may have been intended to be used for such blocks as well (as the back or seat portion, or a tabletop), or it may have simply been the texture copied for the other two textures to be cut from,mars said textures are clearly oak planks derivatives. This was removed earlier than the other two textures in Infdev 20100607.
