Jeff - Parkyn says thus : re Cuidich'n Righ - 'the motto was on the Colours in 1794 but was not officially recognised until 1825. For many years the motto was spelt 'Rhi' and was amended to the correct spelling in 1869' The Duke of Albany's influence existed 1823-1827 after which the coronet and cypher are given as that of the late Duke of York (see 1827 Army List). I'm sorry, but Parkyn had access to records and collections long dispersed so I will stick with him. Just call be stubborn. Regards. David
