These seem to be the the earliest known dated Nuremberg barrels to feature an elongated round muzzle section (German: Mündungskopf): a pair of Nuremberg cast-bronze falconet barrels founded, signed by Endres Pegnitzer the Elder (E.P.G.M.), and dated 1522 - cf. Heinrich Müller: Deutsche Bronzegeschützrohre 1400-1750. Ost-Berlin, 1968; pp. 63, 68, ill.#46-48; p. 69, ill.#57-58; p. 74, ill.#106-107; and p. 105-106.
They are preserved in the Museum at Schloss Heidecksburg, Rudolstadt, Thuringia - together with a third piece bearing the same date, but its muzzle section still showing the older Nuremberg style of ca. 1500-15, for being shorter and still octagonal, though following a long rounded forward section (German: Vorderstück). Notwithstanding that earliest Renaissance taste, this barrel can be identified to have been made after ca. 1520 because of its muzzle; it is pronouncedly beveled, instead of being flat, like the muzzles used to look before the end of the second decade of the 16th century. That beveled muzzle seems to have been kept up to the 1530's, at least with arquebus barrels, whether consisting of a copper alloy like brass or bronze, or of wrought iron.

For comparison: The muzzle sections of earlier cannon barrels are notably shorter:
Der Drach, founded by Jerg von Gunten, also known as Jörg von Guntheim, and dated 1514, shows a short, reinforced and octagonal shaped muzzle section, still denoting the influence of the Late Gothic taste of style (Historisches Museum Basel, Switzerland, inv.no. 1874.94; it came from the former Basel Arsenal.
