Black Watch Tartan 1750's

[figheadair]

From Surviving logistics documents, We know the 77th Regiment had tartan that was exactly the same as 42nd, just with only one Herringbone selvage.

I can't see how a joined plaid could have only one herringbone selvedge?

1740's you had a transition from a red/yellow based tartan by the 42nd into the pattern we know today.

I don't believe that the 42nd ever wore such a tartan.
