These mfgs all stamp the date on the tins, so you might find some aged stock sitting at a local tobacco shop, on Ebay or in some pipe smokers' cellar.
Another thing you might try is to chop up one of your favorite aged cigars and mix 50/50 with some burley tobacco (Kentucky Club, Prince Albert, Half N' Half, Granger, Velvet). A small food processor is a good way to chop up quickly and uniformly. The burley will add a bit of a nutty flavor.
