What type of Thomas is this?

Well changing out the stock shell for a Thomas looking down on a 50 phrase chassis was as easy as this:


But since it has a white deck(and T'nA's don't) my best guess is that it's a Thomas looking down with a gutted T'nA coupler attached to a standard Annie... I hope that I am wrong and that you have found something rare and unknown, but I also hope that your not paying very much to find out either. :S
