This is the correct version of the asymmetrical Malcolm as shown by the woven sample in W and A Smith's 1850 publication 'The Authenticated Tartans of the Clans and Families of Scotland'. Their provenance was 'We addressed Sir John Malcolm of Balbeadie on the subject of his Tartan, and enclosed a specimen, which the worthy Baronet acknowledges to be correct.' D.C. Stewart notes in his Nomindex 'Remarkable similarity to the Double Davidson.'
