1973 on a placard, orange panel or shipping paper
It can stand for either of two ERG 2024 entries: “Chlorodifluoromethane and chloropentafluoroethane mixture” and “Refrigerant gas R-502”. Both use Guide 126, so the number alone is enough to find the guide. On a numbered orange panel, 1973 is the lower number (how to read an orange panel).
