Fred Hanna was a big fan of Marcovitch back in the 70's, but never thought to cellar tobacco back then. He writes about his efforts to obtain some more in his book The Perfect Smoke. I believe that Wilderness and Legends by McClellands might by what you are looking for, as Fred Hanna was the blender on these. One was an homage to Marcovitch B&W and the other was an homage to Balkan Sobranie 759 if I remember correctly. I believe that Wilderness has been discontinued due to unavailability of the Syrian Latakia component, but this was very recent and you should still be able to track some down if you try. Legends is still available, as it doesn't contain any Syrian Latakia. I hope one of these scratches your itch for Marcovitch.
