It is red beneath the black lacquer!
There seem to be only a few places of cleaned white iron.
With the black taken off it should look more or less like a barrel in the Germanisches National Museum Nuremberg; images attached (posted here before).
The barrel in Nuremberg is the remaining part of a tiller/stick haquebut, wrought iron, hexagonal (not octagonal), with changing sides at the middle and a punched decorative lozenge pattern on the heavily swamped and reinforced muzzle head; made in Nuremberg, ca. 1460's.
Its provenance is the famos Hohenaschau Castle in Upper Bavaria; I am proud to say that there is a matchlock musket dated 1633 in my collection that also came from Schloss Hohenaschau. In the 1880's it was in the collection of Heinrich von Hefner-Alteneck, the first director of the then newly founded Bavarian National Museum.
I do not have the exact measurements of this haquebut barrel but I should assume it is about 75-80 cm long and quite a heavy piece.
