Quality Seal Achiev???

[Roberval]

Can you help me with the achievement Quality seal? I've run the entire game 2x interacting with everything I could and didn't get the achiev... All the others achiev were obtained (including Backlands' Explorer and Looter). I no longer know where to try to find items that I haven't yet interacted with... Would you know how many items are to be checked?

It worked! There was a head of cattle missing that hangs next to Dona Firmina's house, in the goats' pen.
