I managed to purchase all six 1988 Autobot Pretenders from a very nice US lady seller. They are all complete. They are all in near-mint condition (bar some minor unavoidable paint scuffing), and has near-perfect stickers with very few instances of peeling.
I am just happy I was able to acquire all six of these guys complete and in one lot rather than have to individually hunt them down. Additionally, I have it on good authority that Sky High and Splashdown are particularly tricky to find complete and in good condition - was great that they are part of this lot.
So, I'm going to say it again, my-pretenders-are-here! Hurrah!

*Sunday edit* Gratuitious shot of the full complement of 1987 Autobot Headmasters Hardhead, Chromedome, Brainstorm and Highbrow; half a complement of the Decepticon Headmasters Snapdragon, Apeface and Mindwipe and two random Targetmasters - Cyclonus and Pointblank (his friends Crosshairs and Sureshot are actually protecting Lego on the shelf above).
