What you see down that stem hole Josh is the light coming from the bowl. I would assume they used a cane drill for the stem hole, as I have found a couple of spindle whirls at the farm also. My son sent me a pic of the preform one, as he has it in the display I gave him. Probably end up giving him this one also, they need to be displayed together, as it tells the manufacturing process. I have a pic of the preform, but the computer its on is outdated (2004), and I can't post any pics off of it. I will have my son bring it with him next time he visits, and post a pic of them side by side. probably just go ahead and send it back with him. He only lives a couple hours away. There are plenty of artifacts to be found still. This pipe was found about 5-6 inches deep. I'll try to get a pic of that hairpin up, that I found about a foot away.
