Shayde, I hope someone out there might have exposure to more of these and possibly have seen such a marking. Being at the forte suggests an arsenal or perhaps makers mark, but might be otherwise as well.
Often coins have clues to state or official markings so maybe a reference on coins might offer some help?
All I could find was 'Eagle of Saladin' which was situated in Egypt mostly.
