I have a box of Partagas Lusitanias with a code of EOG CCNE

I also have a box of Trinidad Super Robustos with a code of EAT CCNE

As far as I can tell these codes mean that the Lusitanias were made at the La Corona factory in 12/99 and the Trinidads were made at the Partagas factory in 12/99. My question is can Partagas be made and in the La Corona factory and can te Trinidads be made in the Partagas factory? Anyone know?
