I think the "3" that begins the serial means 1993, (or 1983). I have one with the same wood, and I would be interested to hear from DH experts. It has a factory stabilizer insert, and I really like the grip.
I read that "brownish" color means 80s, "reddish" color means after 1974, and Martin name was put on DHs around 1998. So am I right to guess that my "brownish" hunter with a serial number starting with "9" is a 1989?
