Sorry I had not popped over here to mention that I figured out who it was.
It was Jonnyboomboom from over at RS. I had trouble finding the post again because it was an old thread, but feel stupid as I overlooked that he had posted the link for me in the ImperialCommandos.com thread that was at RS...hehehe. (I have not had much sleep lately...thats my excuse and I am sticking to it...)
You are right, it was the Cobra Mountain playset.
I will try to repost the links people found at the other sites, so that those here that are interested can have access to the pics as well.
