The value of pipe #297 is 29 points.
Thelma and Paul Dover had an auction on eBay for five pipes separately. They were all but one potential additions to the collection, so I bid on four of them. They identified one of them as "light tan" in color and, sure enough, it is what Venturi called Tan. The Horizon Blue Pot and Ash Grey Apple have joined the collection and the Burnt Orange Billiard went directly to the Pipes for Sale page. Eventually this one was traded to Rick Osborn in a massive swap-o-rama that left us both better off.
