what is an eaa biplane worth

[Salinasflyer]

I am looking at buying an eaa biplane that was built about 30 years ago. The quality of work is good, there is no damage history. It has a midtime O-320 Lycoming with no electrical system. The only downside is that it needs to be recovered fairly soon. Can anyone give me a ballpark idea of what a fair price would be? I saw another plane with an O-290 Lycoming and electrical system sell for $12,900.
Thank you.
