This ointment is a protective agent used to treat the effects of various chemical weapons, namely Mustard Gas. It was typically spread onto the skin as soon as possible, after exposure. Early application was critical to reduce the severity of injuries.

During WW2, civilian were often given tins like these as part of their air raid precaution kit.

This tin here, contains ALL original tubes of ointment. However, over time these tubes (metal) have oxidised as can be seen in the pictures. The tin has a small dent, and some scratches on the lid, however the base (where the instructions are) is actually in remarkable condition. The lid opens and closes well without issue.
