This is my mistake. The error arose because I've a copy of a print of two jocks circa 1875 of the 71st that appear to be wearing Douglas trews, rather than the MacKenzie of the 73rd, but as one is wearing a scarlet jacket and the other a blue patrol jacket, they couldn't be Rifles. It must be a colourist's error at some point. The Cameronians did indeed wear the Douglas tartan, with the usual Rifles' garb of rifle green and black facings and black horn buttons and rank insignia.
