Thank you for the 8page text from the UniKoeln, Erich. The Amtskammer was joined with the Kriegskammer in 1723. The vault inscription is from the 16th century. Based my term on " In the Kurmark, overall administration of both the royal domain and regalian income like customs and tolls lay in the hands of the domain chamber or Amtskammer, formally established in 1615." from Birth of the Leviathan:building states and regimes in medieval and early modern Europe, Thomas Ertman. Cambridge University Press, 1997. If minister for finance comes across as too free a translation, suggest use of (domain) chamber councillor or privy councillor as suggested by TranslOKator and Helen respectively.

DISAGREE with all three choices. Amtskammer used to be basically an administrative body in the old Potsdam Government, that later became the War Department, a.o. See the LAST 5 SENTENCES IN:

is generally translated as Privy Councillor (privy being the privy purse, the sovereign's income). Not sure what the difference is between Kammerrat and Amtskammerrat.
