A genuine Zippo lighter dated 1970 with an American flag logo that retains its original enamel. It features the manufacturer's machine stamped base that shows the correct period Zippo logo and date markings along and the trademark logo, the date markings shows two vertical lines on the left & right side of the Zippo logo this indicates it was made in 1970. The lighter mechanism also features machine stamped Zippo markings and fits nicely in the case and appears to be in working order. Would make a nice M1 helmet band accessory.
