Your Martin logo and riser wood combo says 2007.
For some older Howatt Hunters, these tips come from Howattman:
"If it's riser wood is a reddish wood with a vertical accent stripe, it's a 1970s. If it's a brownish riser made from laminated maple with a reddish vertical accent stripe, it's a 1980s. If it's made from three vertical laminations (dark brown or gray maple, zebrawood and bubinga (the reddish wood I've been referring to), and it is marked as "Martin" it's a 1990s model. In any case, brace height should be between 7 3/4" and 8"."
