Robert: Since your pressing has no label of any kind, I'd presume that it was a test pressing rather than a reject; a rejected regular pressing would have a label. I'm really not making any blanket assertions as to Tone Test disc characteristics. After April 1921 I'd presume that Tone Test records would have paper labels like the rest. I noticed nothing unusual about my discs except the unground edges. I don't know for sure if any Tone Test records were made up with the same selection on both sides, but such a configuration would make more sense for a test record - used to determine which take was preferable. What little I THINK I know about Tone Test records has been learned in the Wile book and Ron Dethlefson's books and my own limited observations. I haven't seen anything written about them elsewhere.
