This is my newest acquisition I bought it today. It is from WWII era I'm not sure if it is civilian or was used by the army, or both, on the box are written the homologation year 1939.

The kit contains: one box with ether crystals (used in case of nausea), two phials of lime chloride (used to clean wound caused by mustard gas, one is crushed and the content spread inside), one iodine bottle (unfortunately is missing), one ointment for burns (used for burns), one wound bandage (in a sealed rubberized cloth probably identical to those used by the army) and a small bandage used to clean the mustard gas wounds before putting lime chloride and with the mention to be destroyed after use burnt or buried.
