I don't know where I would even begin to look for something like that. It's beautiful.
Thanks, I did years worth of looking online and I happened to locate a man who has collected vintage tanks for over 30 years. I kept in touch with him via email, actually more like pestered him, and it finally paid off. He had duplicates of this tank so he was willing to part with one as he had run out of space. Pity he doesn't have a web site devoted to his collection. I'd love to see what he has.
