Black Watch Pipers

I'm sure that OC Richard will chime in at some point but as a starter for 10, you might find this of interest - 42nd Regiment Band or Musicians’ Tartan. In summary, sometime after 1850.

Thank you so much. That appears to partially answer my question, specifically the part about Queen Victoria granting permission for the pipers to wear the Royal Stewart tartan in 1865. Still, this provokes more questions but I will save them for another time.
