Here is a neat photo I stumbled across showing products made in Muncie. Directly under the red arrow is a shelf with Hemingray insulators and bottles. From left to right the insulators appear to be a Hemingray 42, Hemingray 16, Hemingray 62, Hemingray 60, and maybe a CD 302. picture was likely taken between 1925 and 1930 based on the fact that the bottles are present and the insulators are aqua or Hemi blue.
