On your list of found, you have a seperate Battle droid Delux figure..there isn't one. The quote you posted says it is 3PO and battle droid, but should read 3-po with battle droid...

There isn't a battle droid delux...there is a battle droid builder delux slatted to a much later release, but nothing as of yet...

In the package there is a 3-po and a red battle droid with interchangable heads...that is what the quote is referering to.

I hope this helps.

FYI
