I have 3 of these Fn3 Water stand pipes available for sale. These were a batch of special run models by David Saccia of Trackside Details. Only 10 or 12 were made and I have 3 NOS models for sale. The pipe is attached by slip fit to the base and is pinned on so you can remove it is needed. These will never be run again due to the casting sizes and the abuse it made to the equipment for David. That was why he stopped making them.
