Vintage Lotus bass?
 

So while looking around on Craigslist for a head, I found this:

It looks like a decent bass (except for the missing strings and frets), and it's going for cheap.

Anyone have any idea what these things are worth?

About that there are some nice playing ones though.

I see vintage lotus stuff in my area all the time. I would say, given that it needs a refret, it's worth $40-$50 to the right buyer. If it was in 8/10 condition or better, it'd be probably a $200-$250 bass. If it were me, Id trade a fuzz pedal, and turn that thing into a fretless. :)
