I have depicted plain yellow damask standards of the type carried by the other squadrons in the regiment here: https://nba-sywtemplates.blogspot.com/2025/02/three-generic-plain-damask-english.html
During the War of the Spanish Succession it is likely the regiment carried yellow or buff standards with the cipher of Queen Anne; I have depicted such a standard here: https://nba-sywtemplates.blogspot.com/2025/02/three-generic-damask-cavalry-standards.html
But it is perfectly possible these standards were carried later than the reign of James II.
