These are the colours carried by the Duke of Norfolk's Regiment (later the 12th Foot) in 1686. We do not know what colours they carried in the War of the Spanish Succession so these can be used for that war too, until (or if) we know better!
In 1686 the uniform was red lined white with blue breeches and stockings.
Full details of the history of the regiment and its service can be found on the Kronoskaf website here:
