1895, Guy Boothby, A Bid for Fortune, ReadHowYouWant, 2008 EasyRead Comfort Edition, page 266, ‘A nobbler o′ rum,’ says I. Then he orders a nobbler of rum for me and a nobbler of whisky for ′imself.

Carl Wiesenhavern, a man of noble character, and, therefore a man who hates knavery, and has no fear of a knave, answered with his peculiar German coolness, "Here I am, what do you want?" "Nobblers round," was the eager reply. "If that's what you want," replied Wiesenhavern, "you shall have it with pleasure." "We got no money." "I did not ask for any: understand me well, though;" pointing at each of them with the forefinger of his clenched right hand, "you will have a nobbler a-piece, and no more: afterwards you will go your way. Are you satisfied with my conditions?"

‘Fer goodness′ sake, Doreen! Give the gent a nobbler of brandy and stop making trouble.’ It′s the little weasel bloke what speaks. ‘Much obliged,’ I says to him. ‘Nobbler, is it?’ Doreen turns on her heel and she′s about to vanish into the main bar when I shouts after her, ‘Nobbler of Cape, miss!’

This done, he waves his hat and declares his nag can lick anything on the ground—for nobblers round.
