- 1850 — Buchanan (1850 - Clan) (tartans-authority, record)
Because of its popularity the Buchanan has suffered many interpretations and modifications. However, this is now the most popular sett and the accepted clan tartan. It isn't known who changed the original symmetrical design described by Logan in 1831 into this complicated asymmetrical sett but the finger of suspicion probably falls on McIan who illustrated this sett in the Clans of the Scottish Highlands 1845-47 - the popular prints of Highlanders in theatrical poses. In their 1850 book "The Clan and Family Tartans of Scotland" William and Andrew Smith of Mauchline wrote: The pattern here given seems to be universally considered the genuine Buchanan Tartan and we know that it is worn by Archibald Buchanan Esq, of Catrinebank, Ayrshire, whose father's name is identified with one of the first cotton manufactories established in Scotland with Arkwright's improvements." The woven sample in the 1880 Clans Originaux agrees with this sett. This colour interpretation matches a 19th century sample from Kilbarchan Weavers' Cottage. - 1930 — Buchanan (Miller & Lang) Clan Tartan (house-of-tartan, record)
