This hand cannon has a length of 12cm, a width at the base of 60mm, a width at the barrelmout of 50mm and bore of 25mm.
The general shape looks like an adaptation on the Loshult cannon. The base is flat but still slightly rounded, the barrel is swamped and has a rounded swamped ring at the barrel mouth.
All in all i would assign a date of 1370-80s to this barrel based on the previously stated thesis.
Fun fact, when i showed my girlfriend this barrel she told me it looked like a vase, its all the prove i need

hahah
The base is, just like the previous example, circled with a shallow indentation. This could be a method for securing the iron breech plug at the bottom of the barrel (more on this later on).
For now some pictures
