From earlier in the discussion on the 43rd RoF we know that the red stripe was added in 1746 (but we don't know when it was removed), and that the 43rd became the 42nd in 1749. To be honest and possibly much to the distress of purists, I'll probably end up using one of the modern Black Watch in one the more muted ancient styles (http://www.scotweb.co.uk/buy/tartan-...howtab=results) to create the Feileadh Mòr of my 43rd RoF uniform.

Unfortunately the the Army's 1742 Clothing Book shows little more than an artist's impression of the tartan.
