When I come across things like this, the one thing that makes me think "fantasy piece" is if they are fancier than they need to be. Even if Wells Fargo made a special metal tag for a crate with a body in it, I doubt they would have paid extra to have the ribbon engraving. Also for something like that you would want the crate to be very conspicuously marked, like a big stenciled on label instead of a tiny tag that would be easily missed and hard to read if you weren't up close. It's neat, but unless I saw a period photo of one in use I would think it's a fantasy piece
