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. Also available as a 12 string (DM12-1), the Sigma DM-18 was discontinued around 1996.
In 2011 the German AMI Musical Instruments Company bought the Sigma brand name and relaunched Sigma guitars again, including the DM-18 model, this time being produced in China.

I have a 1978 Sigma DM-18 which is a good sounding guitar with the best action I have ever seen on an acoustic. According to your info it is the 1st year of this guitar made in Japan with Martin insignia. What would this be worth?

You show the first Sigma DM-18 as produced in the mid-90's. I own one that I purchased new in 1982. Just FYI.
Sigma cedar top DM 18

I have a Japanese made solid cedar top, mahogany back and sides. Every other one I hear about is spruce top. I bought this new off the wall in 1986, so it may have been floating around for a while. Well-traveled, sounds great, just getting better.
