This is the closest I came, I've stopped developing the flavor as we've moved on to other flavors:
To 27 ml of your unflavored (nic or no-nic)
vaping liquid, add
7 drops flavourart burley
2 drops flavourart virginia
2 drops flavourart desert ship
2 ml pre-diluted seedman commercial
1 ml pre-diluted seedman virginia flue
It wasn't perfect, but getting close.
