Found this poplin jungle shirt a few year ago in a thrift store. They have a distinctive sharp edge on the outside bottom of the top pockets. The only website that had any info on the stock number said the manufacturer started producing them in 1979. The last known order was 5 years ago. Is there any more info about this uniform? Would this have been used in Central/South America in the 80s? The other label is white and says COAT, COMBAT and was made by Atlanco. Tag has no additional numbers. Any information would be appreciated.
