Do they still make firearms by jc Higgins?

Npe- and they never did. JC Higgins was a brand used by Sears for guns mde by companies such as Winchester, Marlin, Savage, High Standard, etc. The guns were marked with the JC Higgins brand instead of the maker's brand. Sears changed the JC Higgins brand to Ted Williams, and in the 1980s, stopped selling firearms.
