So I've been playing around with the idea of automating some of the data fillups on the wiki (Template:Vendor List) and I've noticed that in FCS I couldn't find the possible grade values for the armours visible on vendor lists. Different weapon vendors come with different weapon manufacturer references, but there is nothing of that sort for armour. Is my understanding correct that it will always be in the range of Prototype-High unless the trader/loot location takes part in Artifacts system? If so, do we have any rough numbers on the chance values for each grade? Is there any mod that changes armour grades for vendors without touching the artifacts system?
