Read blind from the painted plaid — de-varnished through the lace whites, then the red and green grounds, the blue guard and the diagnostic yellow overcheck — the recovered sett matches Drummond of Perth, independently of the sitter's name. Domenico Duprà painted it in 1739, which would make it a candidate earliest dated witness to the sett, predating Logan (1831).
