I did very much searched to purchase one of those ultra rare vintage Lighthouse curved tunnels that is until I discovered that the reason they are so hard to find is that they were made of what I call Paper Mache plastic and didn't hold up well over time and for the kind of money they were going for I opted out.
I am thinking the best quality, detailed with multiple use tunnel would have been all the variations of Trackmasters Morgan/Callan Mine Tunnel
