Said to be in the Highland Society of London Collection. The structure of the MacNab is identical with that of the Black Watch; but, by a translation of colours, the most subdued of tartans becomes one of the most striking. D.C.Stewart suggests looking at the pattern through a green filter to see the effect. James Logan recorded this pattern in his book, 'The Scottish Gael' in 1831, despite receiving a different sett from the largest weaving company of the time, William Wilson and Company, Bannockburn. Wilson's MacNab survives as an alternative tartan for the clan. The Baronage of Angus & Mearns (1856) also documents this tartan on P227 as MacNab of Arthurston with slightly different proportions.
