For about 10 years I've owned a Sigma Guitar. I've always wanted to know more about it. (long story short) A man gave it to me.

The inside label reads:

Sigma Guitars
C.F. Martin & Company
Model: CFM - 12N
Serial No. 891000014

(not sure about the last digit, looks like a 4 but may not be)

Made in Korea

Anyone with information, or know a souce to check, please
let me know.
