Here is a shot of the dome artifact. It looks like a gouge was made in the top of the dome, perhaps a thread mandrel or ?? but it left an impression on SOME of the aqua Hemingray made 104's, but NOT ALL of them. It is similar to the dome artifacts found on the Grand Canyon beehives only more of a circle. it is about the size of a US quarter. Some Hemingray made 112's also have a circular artifact, but it is much different size.

I would be very interested in hearing if anyone has a CD 104 with this dome feature.
