Please... don't rely on Wikipedia when you have the regimental site as reference: https://theblackwatch.co.uk/history/
For the record - Following the Battle of Ticonderoga in 1758 where during the attack on the fort of that name saw more than half the men became casualties, the Regiment had been allocated the numerical slot “42nd” in seniority, a number which it was to render illustrious all over the world. In recognition of its worth it was now granted the title “Royal” and was allowed to raise a Second Battalion. In 1786 this battalion became a separate regiment in its own right, the 73rd, and was much in action in India and Ceylon, playing a prominent part in the capture of Mysore and Seringapatam.
As has been indicated above - a lot of the references regarding the bonnet dicing are wrong - it should be royal blue as with the collars and cuffs. The piper would not have worn the Stuart tartan either in 1815 - this did not come in to fashion until later that century.
As a former member of the regiment I would be delighted to help out with reference material or to answer any questions you may have.
You beat me to it mate, I was just getting things together to post ref diced headband. I’ll save it for later as I’m sure it’ll be needed in the future!
