IF it can be "reasonably inferred" that you didn't know it was stolen.
Nonsense, you have no legal claim against the owner. If you contact them demanding a reward, you may be setting yourself up for a criminal charge. You'd be admitting you know the item is stolen and you are depriving them of its use. Plus you are probably going to be investigated as to whether you actually were involved in the theft.
It's an idiotic thing to do.
