Basically it boils down to stated Company Policy, which, when you consider that they'll cover defects back to 1989-90 is pretty darn fair in my book. On top of that you don't even have to be the original owner to get taken care of.

Seriously, you should'nt be too dissapointed by a Company that won't fix a 30 year old product for free, even if it's never been used.
30 years is 30 years..........
