There's another Wolverine figure, named wolverinep4_aofd, that has a similar pose and it's also the same older costume. Looking at my index thumbnails, it may be an update of the older figure. I got that download in 2004, so that one ought to be available. There are a lot of flying poses, with arms outstretched, that should give you a good starting point.
