I'm taking a risk here. In updating the website I came across a folder entitled "Naughtan". Inside I found pictures of the bagpipe with the common stock (to the far right). I also found the picture at the immediate right. I recalled receiving pictures similar to those at the immediate right and found them under "Unknown #15". They are seen in the bottom row and seem to be identical to the picture at the far right. In checking the properties of the pictures, they came to me from Christopher Heyl. Of course, I checked my email archives and couldn't find him. Any help here would be appreciated.

John Naughtan was a turner and musical instrument maker in Aberdeen between 1824 and 1842. The bagpipes pictured here may or may not be his work, but I didn't want to bury them in the "Unknown" area and have them go unseen.
