Malta Convoy is a WWII Simulation of the Allied relief convoy to the British island stronghold of Malta in August 1942.

All The Ships Counters
Mike, the Mad Game Designer has produced more than 7,000 ship counters for use in naval wargames. They cover various navies from 1900 to the present.
I’d suggest that you print them out and then glue them to small blocks of wood for a 3-D feel.
An amazing gift to the wargames community.
