The same is true with Glengarry and MacKenzie. They even offer three different sizes of the Rob Roy!
Of course as discussed elsewhere Matt what you have there is a Scott-Adie bound book of Wilsons' samples and it was the latter who, as 'the' C19th tartans weavers gave us so much of the nomenclature with which we are familiar today. Their 1819 Key Pattern Book includes the following specifications or sizes: Plaid sett, Kilt sett, Coarse kilt, Fine kilt, Small and Smallest although not all setts were woven in all these sizes and a majority of the terms refered to their military tartans albeit Small and Smallest 42nd etc seem to have been for the civilian market.
