The drawing of the spider reminded me that I've been told the current SR&RL turntable at the Old Stone Fort in Phillips incorporates the spider from the original P&R turntable, which was another Portland Company product of similar if not identical design to the one we're building. (The original Old Stone Fort turntable was never actually scrapped but was just left to rot away in situ, and I've seen pictures suggesting the wood was still partially intact as recently as the 1970s.) If this information is correct then I wonder if it might be worth going up to Phillips to examine the spider, as it's likely the only surviving example of its type.
