Corrosion as the reason for extremely irregular inner barrel walls and muzzles can be definitely excluded - it's all massive iron, not rust.

I assume that the plug could be fasten in such a way without welding. It is only the my assumption but not a fact

Exactly, Alexander,

Of course the plug was driven into the barrel when red hot.

A good friend has made this photos at Veste Oberhaus Museum in Passau, in Bavaria South Germany. This little stone bombard or mortar (Steinbüchse / Mörser) was casted from iron. It is dated around 1400. The museum describes this piece as the oldes known example for a iron casted cannon.

In case the dating "ca 1400" is correct this piece would really be an unique object.

Great piece, Andi.
Pity Matchlock, a Bavarian born enthusiast, is not here to comment on this one, which certainly he knows insideout.

Barrel bright orange-white hot and plug cold so as to cause a shrink fit over the plug and allow for forging the barrel.
I would like to have seen them forging these massive iron bits....hard enough to stand next to 28 pounds of welding hot steel (my damascus billets now) let alone some hundreds of pounds.

I plan on making a small cannon next year....I am gearing up the shop with tooling to do so. Should anyone have a reading list for me I'd be happy to read more on the subject. X-rays especially helpful.
