1391 on a placard, orange panel or shipping paper
It can stand for either of two ERG 2024 entries: “Alkali metal dispersion” and “Alkaline earth metal dispersion”. Both use Guide 138, so the number alone is enough to find the guide. On a numbered orange panel, 1391 is the lower number (how to read an orange panel).
ERG 2024 markings for 1391
