It's a 1991 fretless with semitone markers at the top and at the bottom of the fretboard. The fretboard and a new bone saddle are in excellent condition and it is in perfect technical state
OP... with Wal basses, it is customary for TB listers to post a picture of the inside of the cavity cover as well as several high-resolution pictures of the rest of the bass. Of particular interest is the headstock, as your single, low-resolution picture seems to indicate there is something awry with the headstock decal. You are, of course, under no obligation to post these additional pictures, but doing so might go a long way toward alleviating the significant suspicion that your listing is generating.
It's entirely possible this is someone who isn't that knowledgeable (maybe gotten the instrument from someone that died) doesn't know what they have).
Although it can happen, it would be weird for someone to pony up for a gold supporting membership instead of the standard one.
OP- If this is legit, PM me clearer pictures of the bass with your username written on a piece of paper in the photo and I will re-open this thread and clean it up. Until then, closed.
