I'm on the Hampshire coast, between Portsmouth and Southampton

Hi there! I've got the above mentioned bike in what I believe to be classic Ossa green, it's still running, just needs a bit of a clean-up; I've got the original handbook, MOT certificates from the 70s and, obviously, the registration document - I'm only its second owner. I've decided it's time for the old girl and I to part ways but don't have much idea of how much to charge for her; I've tried to have a look around to see how much they're going for but she must be rarer than I thought as I can't find one for sale! Can anyone give me a ballpark figure at all? Thanks guys!
