Hello, Dear Fernando. Thank You very much for the work done. This result show us how important is to do X-rays of 14th and 15th centuries barrels, as they have a fairly complex structure. 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 (

With the best regards, Alexander.
