Wheeled Assault Bridge and Bombard on a Carriage
A wheeled scaling ramp crossing a moat, and a large bombard on its carriage (no text on the sheet)
The sheet bears no writing, only ink drawings. The upper portion shows a wheeled military structure with a slatted covered ramp or scaling gangway, drawn crossing a stretch of water rendered with wavy lines toward a wall. The lower portion presents a large bombard: a long ringed barrel on a wheeled carriage with a cannonball beside the muzzle and a breech-support framework behind. The editorial note records only that the sheet is devoid of writing.

Wheeled assault ramp crossing a ditch
In the upper half a large wheeled apparatus carries a slatted, ramped covered walkway with a triangular bracing frame, drawn spanning a band of water (shown with wavy lines) toward a crenellated wall. It reads as a portable scaling or crossing engine for assaulting a defended position.
Bombard on a wheeled carriage
The lower half shows a long ringed bombard barrel mounted on a wheeled carriage, with a spherical ball drawn at the muzzle and a planked support structure at the breech. The gun is rendered in careful perspective.
Breech support and elevation framework
Behind the breech a timber framework with vertical posts and a toothed or screw-like member appears to serve for supporting and elevating the barrel. A separate planked ground-plan is sketched at the foot beneath the carriage.
