Those look like Japanese Tanegashima guns. The image site for “arquebus” has lots of them presumably because they are matchlocks like European guns which were much heavier and required a rest to fire from.
But lessee now, 500 years ago it was 1516 A.D. The successor to the matchlock, the wheellock had already been invented, some claim by Leonardo de Vinci. By then wheellock guns were already considered dangerous assassins’ weapons since pistol versions could be concealed and fired instantly (no match & faster lock time than the flintlock which succeeded it).
So the Holy Roman Emperor tried to ban them. Fat chance, Beretta was already turning out fine wheellock weapons. Five centuries are not that ancient in firearms evolution.
