Hard to tell with the pictures given. It looks like an Olympic from around 1974-1979 with Reynolds 531 plain gauge tubing in the main triangle. If everything works and the bearings are okay and there isn't much rust then you might be able to sell it to someone for somewhere between $50 and $75. If you're thinking of buying then it represents a good riding bike. Replacing the top and down tube decals will be pricey if you order from H.Lloyd in England.
