Gentlemen, the images and spec. descriptions of culverins i have posted were not selected among "other" specimens "just to make point".
I wonder whether Castano de Sosa is a specialist in artillery, but i realize that the term culverin or cannon, for the matter, is a coloquial means to name artillery guns in a general manner. A culverin of small calibre is not necessarily a gun of such classified type, as a small cannon or a large cannon are not necessarily guns of the cannon class.
You take he cannon yard of the Lisbon artillery museum, one of the the greatest bronze gun collections in the world, where over a hundred examples are exhibited, visibly of all types, and yet this place is officially called the "Cannon Patio".
Having said that, i won't carry on with my trying to compete with those potentially more knowledged on the subject
