Wearing of tartan coats by 42nd Regt Pipers?

[blackwatch70]

Thank you, figheadair,

Could you show the lithograph of piper MacLean in Valletta?

a bit more information about subject.

In 1826 Lieutenant-Colonel Duncan McGregor assumed command of 93rd Sutherland Highlanders, which he commanded until 1838. He dressed 93rd's pipers in kilt, doublet and scarf plaid of the tartan known as Rob Roy, a simple red and black check. Only in 1848 pipers reverted to the dark Government tartan worn by rest of 93rd regiment, but with scarlet doublet.
The McGregor period is commemorated to this day by the red/black diced hose-tops still worn by the pipers of A&SH.

So I suppose this is earliest reference of military pipers wearing full tartan outfits.

I have no related picture, sorry...

Regards,
Mikhail
