At this point you have pieced together the entire corporate history for the shares that you own! If the transfer agent requires for you to get proof-of-purchase for your shares or any other legal matters arise it is at this point where professional help can be a very valuable resource. There are a few stock research firms that are out there for the more complex corporate histories with retructurings and the like that we have not covered. I would recommend Stock Cert Expert(http://www.stockcertexpert.com/
) if you choose the route of having professional stock research service guide you.
In all best of luck in establishing you share's current monetary value and corporate status!
