What can I do w/ a PowerBook 2400c?

A friend of mine asked me to try and sell her like new PowerBook 2400c/180 laptop. Apparently it was a Japanese version with limited release and collectors have been interested in it in the past, but I don't know how to find any collectors. Other buyers looking for a laptop feel it is too old to purchase, so I was hoping someone on here had some ideas. Do you think I can find a buyer for it? Thanks for any help.
