ChiCom North Vietnamese Army Ranger Finder Carrying Bag

Hard to find canvas cover for the Soviet Type 3 Rangerfinder. Rangefinders were long tubular optics of WWII vintage which rested on the shoulders of a AAA crew member. They could accurately judge the distance to the target aircraft. This bag is ChiCom made in 1958. They were used with 12.7, 20mm and 40mm Anti-Aircraft guns.
