Hi Bill! From what I hear, North Carolina is a nice place to land.
I actually lived there once but I don't remember ... I was a toddler in a military family.
For $7.95 you could spend a month digging through the Harrisburg Telegraph. The snippets here look promising.

No ... I can't find anything tagged Harrisburg ... other than tournament buttons with the names you already have listed.
Edit: actually I saw at least one article about the tourney but again not with a name you didn't already have.
Edit #2: I also saw a button for the 11th annual tourney with a picture of the 1932 winner but I don't see a name.
I'll have to look in my files.
The only city I had a conscious focus on was Beckley, WV. I kept finding so much on Beckley that it got its own folder.
Harrisburg, hmmm .....
Yes, Carnelian. (a special marble)
And now I'm thinking we're looking at a different maker than Peltier on the banana-y one. Maybe Master.
... and I like it!
