I lived in Scotland for over a year, and tried Haggis a few times and it ain't that bad,
The ingredients sounds worse than what it actually tastes like.
The new Haggis Playfield design, looks kinda like those Spanish InterFlip pins from late 70s
which had acrylic Playfields, and they have held up very well over the years.
Also Sonic/Segasa used some special coating that made their Playfield look as good as new after 50 yrs of use.
