Freelance Academy Press, dealer in choice codices and excellent ebooks on history, arms and armour, and martial arts, has some books on sale.
They publish books like Steve Muhlberger’s and Will McLean’s Murder, Rape and Treason: Judicial Combats in the Late Middle Ages (2019), a modern moral criticism of warfare in 14th century France wrapped around a discourse on Geoffrey Charney’s questions about the joust, tournament, and war, and Ellis Amdur’s Dueling with O Sensei: Grappling with the Myth of the Warrior Sage (2016). They also carry Dr. Manouchehr Moshtagh Khorasani’s books on arms and armour in Iran in the Islamic period, and La Belle Compagnie’s beautiful 1381: The Peel Affinity.
I have not had a chance to flip through their publications since 2014 except for the one on Charny, but their books are always well edited and laid out.
Edit: FYI- they are US based, international shipping may be pricey at the moment.
