My guess is also that the tartans do not go with any of the units mentioned. (The studios probably grabbed a generic "bagpiper" photo.)

With the last cover, the bass drone - the longer stick, second from right - appears to be in the wrong stock. It should be one more position to the left. It's possibly the pipes were assembeled correctly, but laid out wrong. I've laid my own pipes down like that before - had to double-check when I picked them up!
