Anyone maintain a list of which FFing items are the same thing?

I know the old Okuma Airframe reels were the same as the Redington Crosswaters and one made by Cabelas.

Others? Seems like the Orivs rods are very similar in description to the Sages.

I would like to get a list started, if for no other reason than to be able to get spare parts for those which need them. I have Airframes and Crosswaters that I can use interchangably.

Thanks!!
