Wear on augers and clean grain elevators, etc., doesn't really prove a lot on an old machine, IMO. They can and do get replaced. If the paint on the clean grain elevator is nicer than the rest of the machine, then you know it likely was replaced, and the combine has more than 700 hrs. Look it over good. It's mechanical appearance should be very good if those hours are correct. Like hillfarmer said, it could have been a haven for rodents sitting for two years.
One area I look at when trying to determine hours on a combine is wear on the side sheets where the chaffer frame seals rub the sides of the combine.
I realize that can vary depending on how much dirt the machine ingested, and what soil type the farmer had. Sandy soil wears things out pretty quickly.
But if it has 700 hrs, it should have basicly no wear on the side sheets.
If they are worn nearly through, it's got 5k hours.
