My dad has been doing a bit of sorting out. He's given me his old Olympus OM20 which came with a 35mm (guess this is the kit lens?) and a 200mm Sirius zoom telephoto by the looks. There is also a flash gun. Now I've not much experience when it comes to film cameras and he has said I'm more than welcome to sell it so that I can put it towards my Nikon fund, which I may just do. It literally hasn't been touched in over 20 years, and it was a slightly odd feeling unpacking it from its case. It all seems to be spotless, and even comes with it's manual. Apart from Ebay, is there anywhere you recommend where I can find how much this lot is worth? I'm in two minds to be honest, but I definitely wont be using it and it seems a shame just to keep it boxed up.
