With the talk lately about the blue and green tint Hemingray - 56's being so uncommon, I was curious to see which ones I had. It turned out I did have a green tint one along with a light straw. Both were found along farm phones lines near here in the early 70's. I remember finding more of the light straw ones. The mold number and date are 15 - 52 with one dot on the green tint one.
