Looks like Blackwatch?

Quoting from a history of the regiment, published by the
Regimental Museum Argyll & Sutherland Highlanders:

"The 93rd also wore kilts of the same tartan, which in official records is also sometimes referred to as the Sutherland tartan".

Later in the same publication:
"The "Sutherland" tartan, as worn by The 93rd Sutherland, and later Argyll and Sutherland Highlanders, is considered to be "Government" but in a lighter shade".

In another published article by the same museum:

"The 93rd wore the same tartan as the 91st. Lochnell called it 'the Campbell Tartan', the 93rd referred to theirs as the 'Sutherland Tartan'. It is exactly similar to that worn by the Regiment today".

Since the Regiment was raised at the behest of Elizabeth, Countess of Sutherland, was assembled initially by her cousin Major-General William Wemyss of Wemyss, and staffed early on primarily with Sutherlands, MacKays, and Wemyss' from County Sutherland and surrounding counties, I definitely think the Sutherland name should stick to the tartan worn as well.

It goes without saying that the 93rd "Sutherland" regiment kept the 93rd regimental number, even after amalgamation with the 91st Argyll, who lost theirs in the process. The glorious battle history of the pre amalgamation 93rd Sutherland Highlanders-"The Thin Red Line", especially after their service at Lucknow and the Crimea, had more than a bit to do with this I'm sure.

During the 1857 Indian Mutiny the 93rd earned Seven Victoria Crosses during the reliefs of Lucknow, 6 of which were won in one day. The Regiment was a favourite of Queen Victoria's.
