Hi my fellow Dutchman
Welcome to this forum and congratulations on that amazing breech loading cannon. I never saw this one before, it looks like a cannon i found in this illustration from the manuscript "Ms. germ. qu. 14 (Ausst. 48) - Rüst- und Feuerwerksbuch" Made in around the 1500s. That decoration was in use quit a while if i am not mistaken, but i too never saw it on such a cannon before. I would however dare to say that this cannon was originally made somewhere in Germany, but correct me (anyone) if i am wrong)
