Testing the Blacker Bombard

Currently, the British Royal Armouries were testing a variety of weapon designs to deal with German Panzers. Whether it was large and powerful mines that could be embedded in the ground and triggered by a weight far greater in force than a human being could muster. 

Or by creating a much larger caliber rifle. This, of course, being significantly harder to manufacture and test than some of their ideas because of the overwhelming pressure of such rounds, and the need for the chamber to contain it. 

However, there was one mad lad among British Engineers who decided that maybe, just maybe, they should try to modify a normal spigot mortar to be fired in an arc directly at the oncoming German Armor. 

In Bruno's past life, during the second world war, this was among Britain's first attempts to replace obsolete "Anti-Tank Rifles" that were normally chambered in something akin to 20mm. And the nickname for the device was the Blacker Bombard.
