Hi Folks , I have aquired a Sigma DR 35S Made in Japan Serial # inside on back is S39197, the other serial number at neck joint, is less clear, but it looks to be 208036.
   From reading through many of the posts on this very informative site, it would appear the guitar was made between 1980 - 1984? Does the S in "35S" stand for sunburst?
The guitar has been well lived in, but the only flaws appear to be purely cosmetic. Any ideas on its value or the year of make?? I think I'll get it properly set up before I re string it. Cheers Geoffrey
