A medieval hand cannon ... sturdy as can be

[fernando]

I have a dozen of these things in my collection; but never one so thich and heavy as this one.
With 29 cms length, this is not only the longest one i found but, with its rather thick walls (32 m/m muzzle with 9,5 cms diameter and 9 cms. tickness at bottom), it has a 'modest' 15 Kgs. weight.
With an octogonal section, we may place it as XIV century gothic style ... an assertion subject to correction.
Its forging is quite a crude one, with a rather irregular bottom; can't even stand upright.
I don't know what to say about that peripherical welding cord around the touchole. It may have been a way to prevent the ignition powder charge from spreading all over, assuming a very worn touchole area but, when this addition took place, i don't know. Maybe you guys have a knowledge on the welding (soldering) area an wish to comment about it.
