The Sigma DM-18+ was introduced around 1978 when Sigma was the Japanese budget line of Martin guitars. The Sigma model names were chosen to match with Martin model numbers: the solid spruce topped Sigma DM-18 was closely modelled on the Martin D-18 dreadnought.The guitar has some slight blemishes on the lacquer of the neck. Purely cosmetic.
