Funds available: De Reimer family is the richest family in Formaroth, enough said :p

Army size: Like all other armies it's only the trained soldiers that will have access to metal Armour. The militia will at best have leather Armour, spears and shields. As I mentioned before Cawanor has the smallest military with around 8,000 soldiers. In comparison to Uzgob which has the largest military with 18,000 soldiers. 

Access to raw materials and smiths to use them: Considering Cawanor's main industry is mining and has a large number of skilled smiths (due to smithing being a large part of Cawanor's industry). So Cawanor has plenty of access to both.
