The few photographs I've seen of early 19th century army kilts show quite small sett sizes.

Perhaps the large sett was intended for the belted plaid? I can't remember when they were abolished in the army; I don't think they would still be worn in 1819, but perhaps by officers.
The 1819 counts for plaids, of which there is one each for Officers, Sergeants and Privates all give a sett size of about 13.25 inches. The weaving instructions suggest that the counts are post 1800 so are probably contemporary with the 1819. I think Bob Martin's book mentions when the plaid was dropped permanently. I have a feeling that it was c1820-25.
