Canons

Aren't these too heavy/massive for swivels ... and no aiming tail

At only 65cm long & about 35mm bore these are of correct size for swivel guns & although some swivel guns had an integral 'tail', or 'tiller' many did not and the tiller was either a separate item attached to the cascabel or incorporated into the swivel 'yoke' mounting.

Although it won't make a lot of difference it would be helpful to confirm if the measurement provided is overall (face of muzzle to rear of cascabel) or as was officially done (face of muzzle to base ring) ?
I am assuming it is overall.

It’s correct overall length. The light spot in the gun barrel is from a torch on the touch whole….

Are the bores cylindrical, without constrictions or irregularities from casting? For guns that are meant to be shot, this is important. Besides the bores going all way back to the touchhole.

The reason I ask is that a little bird in back of my skull is suggesting that these might be barrels from small saluting cannons. Make to fire blank charges, of course. If they came from a castle in south Germany, it's not an unreasonable suggestion because the landed gentry / upper crust who lived in these places did like to shoot off festive salvos on special occasions.

As far as I can see this canons are made of cast steel and not of bronce. As this material was not in use in central Europe at the time when this type of canons was in, both should have been made in Scandinavia, perhaps in Sweden.

With the description 'cast steel' do you actually mean 'cast iron' ?

i mean cast steel, but perhaps I am wrong. A friend of mine, owner of a very famous artillery-museum and a real specialist told me that this canons are probably made of cast steel The production methods of making cast steel had been invented in the 1740s in England but came into use in central Europe not before the 1840s.

The common use of cast iron versus the rare use of cast steel in this period aside the two metals display markedly different corrosion characteristics and these guns have every appearance of being made of cast iron. I would be astounded if they were anything else.
Cast steel was a technology that was neither very practical nor affordable until after the introduction of the Bessemer process in the mid 1850s.
