at a local flea market type festival, i found a "ROYAL STAR" WINDKING LIGHTER stamped from Japan. It is a zippo look a like but more slender and shorter. it is 2" long and 1 1/4" wide and 5/8" deep. i can not find anything on this lighter... any suggestions??? please help. I've researched that most "zippo" look alikes were manufactured around the Vietnam war era, but i can NOT find royal star lighters in this style around this time.
