Need help with richtofen's grand scheme in Call of duty Black Ops

Hi guys, I am thinking about tackling this easter egg soon but i heard that you need the focusing stone and the golden rod by completing the easter egg in the other maps. I don't have any of the other map packs except resurrection. I have been reading this guide here and there are no mention of the rod and stone http://callofduty.wikia.com/wiki/Richtofen's_Grand_Scheme

I don't remember ever having the stone or the rod in any of the games i played online or solo. can any one confirm that you need to have these items?

also, I welcome all the help I can get if some one wants to play with me my psn id is hitman480

bump

BUMP!

thats the first thing i thought of,but they are sooo dead. I'll get a reply in like a month.
