Only a tiny proportion of wines get better with age. Even fewer improve over ten years or more. For a wine to still be great after 40 years it has to be stored very well - which I comment on in this case - and it has to have huge potential - which I don't think your wine ever had. To be honest, I'd be surprised if it is even still drinkable at this stage. Sorry!
