Sorry, no etymologies found.
"Here, Lucy," Tam called out, passing her a battered mug, "p'raps a bit of rumfustian will change yer luck."
Alarmed by the sudden drain of color from his captain's face, one of the powder monkeys rushed forward, still clutching the bottle of whiskey that had kept him company after his mates had passed out from a surfeit of rumfustian and excitement.
I say "almost" because immediately above the target word were: rumgumption (which in Scotland and in the north of England means ` keeness or shrewdness ') and rumfustian (` a hot drink composed of strong beer, white wine or sherry, gin, egg yolks, sugar and spices').
