The Ebay offering of Perfect 12475 must have telescoped the info from the two sides, since Dalton is listed in the discography for "Don't send ..."
A Walter Dalton was listed much later as performing 'hill-billy' with the "Pine Hollow Jamboree." I don't know his music. Don't know if he is the same as the ballad singer.

I see "Lone Star Ranger," Perfect 12570, Walter Dalton, (Flip Dust-pan Blues) is being auctioned tomorrow as no. 718 at www.bluesworld.com/78Auc33.html
