Since the historical sources do not give a clear answer, it is just an educated guess that the grenadiers of the Royal Écossais wore the
personal tartan of Lord John Drummond (1714 - 1747), but it seems quite obvious.
.
The Royal Écossais tartan is a reconstruction variant of the personal tartan of Lord John Drummond, Colonel of the Regiment Royal Écossais (1744 -
1763), shown in a painting which was painted by the Italian court painter Domenico Duprà in 1739. The portrait of Lord John Drummond, which is in the National Galleries of Scotland, served as
the inspiration for R.L. Heil of Eighteenth Century Tartans who reconstructed the Lord John Drummond tartan in 2013.

We, the members of the La compagnie des grenadiers du régiment Royal Écossais re-enactment group, proudly adopted the tartan of Lord John
Drummond as the regimental tartan for the portrayal of the grenadiers of the Regiment Royal Écossais.
