I have a 78 in nice shape. hard wood paneled bed, interior is done. no rot. mechanically very good. Not sure on your budget? I've only just kinda got the idea of possibly selling, so early days for me.
If I'm honest I've found it a little hard to price as there's not too many about. I've seen one locally last year at £11500. That's strong tho I think, although he did sell it. I think I'd price it at £10k.
