Is there a way to get content info from a barrel Gob?

[luk32]

This is not really an issue, but I hope here is a fine place to ask.

I think it's possible to get barrel content type without opening it, because barrels are rendered differently based on the content type (e.g. they get a different sticker).

I saw that WItems have a way to get contents. I could also find barrels by filtering gui.map.glob.oc. But I don't know how to pick right one, for example with wheat seeds, or flour, etc.
