Without photos, it is a bit of a crapshoot. Are you talking NRA rating of good (which really isn't paticularily good, in my opinion) or are you saying good as in something positive.
The no4mk2s were imported a number of years ago in the grease, and mummy wrapped in newspaper, and these days will fetch $600-800 in that condition. However, if it has been well used, then value diminishes greatly. Bottom end for a full wood no4mk2 with accessories would be in the $250-350 range. Better condition will work up from there, but no matter how you look at it, it ain't a LongBranch.
