Default Mounting an early cannon

Some time ago I acquired a cannon that I subsequently mounted on a tripod-like contrivance, viz



I used the welded on pivot contrivance as a point of articulation...



Generally cannon are mounted using things called trunnions


Mine has no trunnions so I sort of assumed that it would not be mounted on a carriage per se.

Now recently I was perusing the Zeugbuch Kaiser Maximilian (Book of armaments which is worth a gander). I knew there were examples that resembled my cannon but, for reasons lost in the mists of time, I never paid much attention.




That is mine and they mounted it on a carriage. Note that the pin affixing it to the carriage is below the body of the weapon.


Now generally, elevation adjustment is accomplished by use of a qizmo that lifts the rear of the cannon. Here no vertical movement is possible. How did they aim it?

Damn odd.

BTW this book definitively establishes a terminus ante quem of ~1500 for this type of cannon. I have no problem dating it at ca. 1500.


Book of armaments ...

Do you have more photos of the bore, vent, & any other details as well as measurements? Is it iron? The corrosion & lighting make it difficult to tell, but if it is, it very well might be an important early 16th century wrought iron falconet. Corrosion may make it difficult to tell, but if it is of that era there may be proof or guild markings of some kind.

As for adjusting elevation, these early gun carriages often had accommodations for a wedge, screw, or cranequin at the cascabel so the barrel may be adjusted via it's trunnions or pivot. Larger fixed barrels can be adjusted by blocks & wedges under the tail of the carriage stock, or by digging a pit. Picks, shovels, & carpentry tools were essential for an early artilleryman, and such tools are frequently illustrated alongside the ordinance in Maximilian's book.

Sorry, got caught up.
Length o/a is 45". Bore ~1.25"

Iron

There is what appears to be remnants of paint on the entire length of it. The only illustrations that I have come across are in Max's book.

Thing is that if it is mounted in a carriage (as illustrated ) there is no play, the only way to have adjusted elevation would be to raise or lower the trail.

I have gone over this object fairly diligently and have not observed any marks. I shall take it out in the sunlight and go over it again.

BTW ... it was loaded with powder. I flushed it out onto filter paper. It burned but poorly.

In "Das Feuerwerkbuch von 1420" I found these drawings showing how the elevation of the cannon was constructed. May be this is of interest for you.
