I've just released three new 1:600 scale Age of Sail flag sets, now those of the Holy Roman Empire, British White Ensign (1707-1801 version) and John Martel pirate. As customary amongst us, each set comprises one large ensign, two medium-sized flags, a bow jack, and a commission pennant.
All three can already be found at Minairons' website, 17th Century and/or 18th Century naval flags sections.
