Looks good.
The Spider and the Wolf could arguably be called a scenario book, although it contains only two boardgame scenarios and one barroom brawl for MechWarrior RPG rules.
Lawyers, Guns, & Money (for free download here from classicbattletech.com) is a pretty cool canonical scenario book in PDF.
Finally, there's FanPro's apocryphal German-only
Ronin! scenario book. The book itself is apocryphal, but its content and storyline was used for the fully canonical Brush Wars sourcebook.
