My Professional opinion.............
Check out the down tube at the front...............as the corrosion looks like it might come from a front end shunt....i.e. stretched paint/tubes ........
It isn't a well looked after Rourke...........(PS warning) but the front end doesn't look right.... had it been, it would be OK - check out the chrome forks as well, as it will cost you a small fortune to sort....... Need to look into the rust before committing......
