Fantastic,
Thinking we already know all that has to be known. Yet what more we have to know before we die  .Thanks a million for sharing this, Andi. Will obviously save this picture to my archives. ... Assuming i will never get to visit that museum ... much less the Great Wall .

Curious it is, no doubt; fantastic? Possibly ...
How would it have worked, with two touch holes?! I'm afraid what really puzzles us is the fact that that piece of cannon must have been crudely altered some later time.  Best, Michael |

After a quick browsing ...
It seems as these things were not that uncommon in the Great Wall arsenals.
More uncommon appears to be nowaday's knowledge of how they worked in those days http://www.greatwallforum.com/forum/...te-cannon.html I still call them fantastic ... almost unbelievable

Hi 'Nando,
This one I completely understand: a breechloader with the interchangeable breech missing. But two touch holes in line??!! Best, Michl |

I would surmise that the orifice on the back has a different purpose

To my unexperienced eye, the hole in the back seems to be horizontal. I reckon i see various holes but only one touch hole. Also the breech cavity doesn't seem to accomodate a classic rotating cilindrical re(chamber), but rather a squared frame for a lid. There ought to be an explanation for such an atypical system. . |

Exactly, 'Nando,
The hole in the muzzle plate/flat is highly unusual and dangerous, and the lateral damages seem to be rests of former integral stone trunnions, which would make much more sense than drilling a horizontal hole for a transversal bar into granite ...
