When I first read about this toy castle I was determined to find a copy. I was surprised that a set like this was available for the price of $1.00 (well 1.49). I don’t suppose that it is true to scale. It might work for Z scale or if you wanted to use it on a N-gauge layout I would suggest placing it toward the back of the layout. In either case I would leave the figures out, in that they are close to 1/72.
