Hi Jack,
I'm sure other club members will be chiming in soon with their thoughts on this topic, but I thought I would throw in my two cents.
As far as the value of the instrument, this is difficult to determine. It would depend on factors such as wood options and any unique features the instrument may have. Being a 6-string and being in great condition are working in your favor for price. Being left handed may do the opposite. It is hard to judge what kind of market exists for a lefty 6. From my many months of eBay shopping and general overuse of the internet, I would estimate that this instrument would fetch between $1500 and $2000.
As far as HOW to sell, you've already posted here, which would be my first recommendation. If there are no takers here in the club, you may want to try posting ads on sites such as
www.bassgear.com or
www.harmony-central.com. I have had mixed luck with those type of classifieds. If you use one of those, watch out for scammers. If you smell something fishy, you're probably right. If you have no luck there, I would then give eBay a try.
Hopefully someone from the mothership will get back to you soon with the information from the build record, and that should help you narrow down an asking price.
And as I'm sure the Pauls will tell you, nothing helps like PICTURES, PICTURES, PICTURES!!
Sorry if this was a little rushed, but my boss prefers when I use my computer to do work. Go figure.
