Years back I had several Castello "Occhio di Pernice" (Eye of the partridge) pass through my hands. They were similar in that they were all crosscut. The front and back of the bowl had horizontal straight grain and the sides were birds eye. I hate to say it but from one of the pics of the side of the pipe it doesn't look like an Occhio to me. Also, looking at the shape of the pipe it lacks a certain elegance you usally find in Castello shapes. Frankly, I can't help but wonder if it's a fake. These are just my impressions for what they're worth.
