More late 15th century stocked arquebuses from Diebold Schilling's
Berne Chronicle, 1483.
Thank you for the hint, Alexander!
Please note that stocks are left in natural, unvarnished surface while the iron barrels seem to have a brownish color, and the guy on the right loading his gun, with the bag containing the accouterments at his feet.
In the right foreground there is the most remarkable utensil: a
Zeuglade (arsenal chest) containing paper cartridges and balls for the arquebusiers!
Best,
Michael
