hi will 1000, from what i can see, it is a 4-6-2 and not as you have said above. i have never seen one like this, but i do have one on a board of similar fashion and without the coin that cost me £5 a few months ago. i also have a genuine hornby 'limited edition' 4472 flying scotsman with double tender and that cost me about £72.95 about five years ago. sorry i can't be of any further help on this for you.
