Unfortunately, we can see this kind of work very rare. It is obvious that the barrel is spiral welded. But it's not the most interesting. The most interesting thing is that the shank of socket is secured not only by press-fitting in the channel of barrel, as due to the fact that between the socket and the shank is a tapered neck. it appears that the shank is held by the sleeve (looks like cup with hole in bottom) into the breech, as the diameter of the holes in the sleeve is less than the diameter of the shank. And it keeps the clutch due to the fact that it's a taper extending from the front end to the rear. I think that way of assemble was such that the shank of the socket inserted into rear end the barrel, then the breech sleeve put on the rear end of the barrel, than sleeve was rolling around the tapered neck of the shank with by a hammer. Do you have any pictures with higher resolution and a more detailed x-ray of the front of the barrel? If so, could you throw on my e-mail ( Spiridonov12@yandex.ru )
With the best regards, Alexander.

What a perfect and comprehensive interpretation of the subject, Alexander. The drawing shows a lot of knowledge and speaks for itself. Thank you for having posted it. I have already emailed you the original high resolution pictures. The part of the barrel mouth is not so much complated as i told the X-ray operators to focus more on the breech section.
Once more thank you so much for the lecture.

A wonderful thread! Matchlock would be weighing in I'm sure.

To see the x ray scan that leaves a clear image of the hidden construction details is something we only dreamed of just a few years ago.

Thanks!

Amen to that ... both sentences .

Thank you very much Nando for these X rays of the Tillered hand cannon. It confirms the idea i had about these guns that they are of wound band iron. Combined with the reeinforcing iron bands this could be one of the earliest tiller guns in the world. Wound iron barrels where one of the first type (together with cast brass) and would be the main way to go up to the early 15th century. The only thing withholding me from dating it to the early 15th century for sure is the flared muzzle ring. From the top of my head these where in fashion from about 1430s upward to the 1460s..

The construction of the breech reminds me of some of my tiller hand cannons as well as the montjuic hand cannons, both in Michael's collection and mine. They could be related?

Well Marcus, concerning the origin of this gun and that of its relatives; we may know their provenance but the origin is another thing. We know that a series of these items were property of Montjuic Castle, but not that they have had any action in that place. We also know that museums do not necessarily exhibit the material of the castles where they are situated, the items in exhibiton being a product of donors ... collectors, families and so. Remember the inscription painted in one of these pieces, from Michl's collection (see post #89 and previous):

Also interesting to notice a detail in the breech construction (shank) in another specimen provenant from Montjuic, also from Michl's collection (see picture attached).
I would then, based on their museum provenance region, donor origins and all, reduce the range of possibilities for the origin of these tiller guns to being Spanish but, what do i know ?
