A similar brass barrel, ca. 1490-1500, probably founded in a Nuremberg workshop, and in excavated condition, the breech struck with a Gothic minuscule s mark, fetched 8,000 euro including buyer's premium at Hermann Historica's yesterday.
It is mainly the short and pronounced octagonal muzzle section that accounts for the assigned date.
Here are the details.
