First of all,no village blacksmith,in his sound mind,woud buy any of your looted longswords or milanese breastplates.He wouldnt have enough groschen. And if, to whom would he sell them? Local peasants? He might be willing to buy some iron items to reforge them into nails,plows,horse shoes and such. If it was not too much trouble for him. It means for the price of scrap metal.His masterpiece in terms of military equipment would be scythe made into some primitive glaive.
Second,no specialised master swordsmith or armorsmith would buy any of your crappy loot. They were crafstmen working with custom orders. They had no interest to buy some used up,beaten and torn piece of armor soaked with blood of very doubtful origin and quality. Specially plate armor was custom made,taylored to the figure of the customer. Such artisans were flocked into guilds in big towns,as production of advanced high quality products required a complicated chain of subsuppliers. Thats why these armors were famous by their place of origin = Milan (for italian style) and Augsburg,Magdeburg,Nuremberg for german/gothic style armors. You would not find such masters in countryside province shaitholes like Rattay.
Complaining that Uzhitz doesnt have such loonatic to buy your scrap…
Looting of dead bodies (even enemies) was largely considered as sinful/immoral by church and society. It was also not worth/practical to strip dead bodies of armor (after beating your enemy with warhammer you can imagine the mess).While in game Henry can do it in a blink of an eye,in reality only those with strong stomach would do it. Usually only best pieces were removed from body,like jewelry or much easilly removable helmets (assuming you didnt process your opponents skull into potato mash during duel).
If someone was really determined to get that beaten up plate armor with torn hauberk from enemy (that noone would buy for any reasonable price excusing the effort given),he would resort to chopping off that particular limb to which the armor has been attached. Weapons of still good value were usually collected by local military authority and were repaired/stored/reisued by armories.
So more realistic choices for Henry to sell metal loot would be:
- Damaged beyond repair= iron smelter
- Still usable = local armory in Rattay BUT with limited demand. If you bring 1000 swords nobody needs,you will have to proceed according option 1 (or drop them on the pile of manure)
