Not sure exactly what my grandfather smoked; however, I distinctly remember that he has some straight stemmed black rusticated pipe and a large white tub of tobacco. Since he lived in a very small lumber mill town I assume that it was an OTC blend and am inclined to believe that it was Captain Black.
I had an uncle, my grandfather's brother, who smoked old burly blend like PA, Granger, Paladin, ect. What is amazing is that he often would set around the campfire and make his own corn cob pipe. After fashioning the bowl he would take a long piece of metal and heat it in the fire to burn/bore a whole in a random piece of twig he whittled for the stem. This would be in addition to the one briar pipe he had.
