Almost certainly of Nuremberg make, wrought iron, octagonal, of tapering form with slightly swamped muzzle, deep and large touch hole with rudimentary pan moulding, gunsmith's marks: three circles in line and a series of illegible symbols (a date?), surmounted by a cross.
Originally most certainly not individually stocked but part of a mutlibarrel cannon arrangement.
Overall length: 36.8 cm, cal. 29.5 cm, width at the rear 9.4 cm, width at muzzle 6.3 cm, weight ca. 7 kg.
Rumor has it that my friend Fernando will quite soon be able to present a very similar item ...
