Ask him to email you the full size photos via email. There's definitely a Bob Jackson decal on the downtube, that much is clear. That looks like a recent build, with Honjo hammered fenders and probably a Sugino XD crankset, and those look like $50 Nitto water bottle cages. Strange to have found it at an estate sale. Some unfortunate iBOB had an angry spouse or met and untimely end.
What kind of rims would be Schwinn Approved? They look modern. To give the seller the benefit of the doubt, maybe something on the bike is branded Paramount. I've known seller to name a bike after some miscellaneous part on the bike.
On the other hand, perhaps those photos were swiped from elsewhere on the internet, and this is a complete scam.
Nice bike, though!
