There used to be some pretty cool tanks on the Dolphin Blue site as well which I managed to snag before the site went down. Now if I can just find them in my files...
I have all of those tanks, the iso gawara and a small dive boat that used to be available on the same site as the gawara. If anyone wants them just let me know, or i could host it and post the link, if it's ok to post it
