The Scottish Horse and Scottish Lancers look like they are both the same photo (both lancers).

Fake News!  The correct picture was there all along.  There is no hint of a cover-up of a mistake here, because there was never a mistake in the first place.  To say anything else shows you to be an Enemy of The People.

Nothing to see here, move along, move along...

I think that you just out-Trumped Trump with that one, Peter! Well done!  :)
