If someone still owns the T.C. then I suppose I should contact them and maybe try to buy it from them or reach some sort of agreement. I guess this might be the case when a company has been merged with another.
But what if the original manufacturer has been liquidated and simply does not exist anymore? Who owns the TC? I guess nobody. The CAA maybe?
That's the way I see it, but since I am no lawyer I could be totally wrong. Opinions, anyone?
