US Surplus Chlorination/Purification Kit Vietnam War

Early Vietnam War Surplus United States Military-issued, troop water purification kit. Dated 6/68. The United States joined the war in March 1965. This was an effective way to keep the troops moving. Surprisingly, all the vials and glass bottles have survived. This whole kit is in great condition and comes with the instructions. The testing tables haven't broken down. 

Cool piece of survival from the Vietnam War
