"Master Rounds can be given to the Tailor before he asks for them, but the other three components must be given to him in order."
The wiki currently says this, but just now I gave the engineer the keys and coins for Balck Powder Mine before I gave him the armor. If someone else can confirm giving him the Hegemoney credits before he asks, we can amend the page to: "Components can be given to the Tailor before he asks for them."
