Thanks Ken and Arnold for your replies. I returned the bass today and asked about the scroll and tuners. Different guy today and he had no idea. I asked about taking off the plates to see what might have been there before and he said it would take too much time & effort and might cause damage.
I guess I just don't know how much this bass is worth if it's a decent sounding instrument (10K-20K for sound) in decent playing shape, but no one knows the maker or where it's from, or seems to be interested in it for that matter. I forgot to ask them to ask the owner about what she knows of the origin, scroll, and tuners. I'll call them tomorrow about that.
Just a hypothetical question: Let's say this instrument is German or Bohemian. What kind of price would you put on it? I understand if the question isn't really fair considering the crappy pictures I took of the bass, and not before hearing the instrument.
Thanks!! I greatly appreciate the help!
