This is off topic but I know the depth of expertise that some members have. I have a powder flask that is a Prussian Army issued military flask from the mid 18th century. It came with a model 1742 Hessian flintlock cavalry pistol. The flask is regimentally marked "HRI C25". I was wondering if anyone might recognize these markings as to what regiment is represented by the HCI marking. Thanks for the help.
