Star Wars Micro Machines window boxes, rare or not?

[BaronSat]

Hello,

I'm currently putting my MM collection for sale, so I tried get informations and found that some of them where unknown???
They are transforming heads in window boxes like this one:

I also have a Tie Fighter pilot, Rebel Pilot and Imperial guard, if you want to see some pics I'll be pleased to publish them.

So I hope to find some fine SW collector here that can help me... "you're my only hope"

Thanks.

PS I post more pics on rebelscum Micro Machines forum.
