Dilemma on a bilbo

[midelburgo]

Now, imagine I did not find out about the sword being a replica, until, after paying for it, I would receive it several days later.
Probably, I would be outraged, and ask for a return and a refund. Even if there was not deceiving intention by the auctioneer.
This is the sword, only one of the pictures has clear clues to think the sword is from a later period.
