Kingsport, Tenn. While they were bottling Pepsi-Cola from 1919 until 1924 they changed their name to the Kingsport Chero-Cola Bottling Company in 1924 so there should be a twist style at least from this company, but none have come to light yet. There is a later 1940's style twist Chero bottle though.
You already have Bristol on your list, so here is Johnson City Tenn.
That pretty much covers the bottlers in my area; however, I did find where a Chero-Cola Bottling Company was selling it's operation in Mullins, WV during the mid 1920's so there may be some from there.
