mounting modified as a self-propelled carriage on a Ford
4x4 3 ton truck. Power transfer and elevation with
joy-stick control, driven by PTO. Firing was by a
solenoid or a mechanical linkage operated by a foot

Additional: Four levelling jacks (front,
sides and rear) were used to stabilise the vehicle. The
rear axle was lockable, which made it possible to
"stop-and-shoot" without using the jacks.
Another vehicle with the Bofors 40 mm gun was the
"Carrier, 30 cwt, SP, 4x4, 40 mm AA (Bofors)
Morris-Commercial C9/B 30 cwt". The equipment was
designed as a dual-purpose weapon for
anti-aircraft/anti-tank use. Several marks existed, but
the most common utilised the 40 mm Mk 5 mounting. The
frame had no foot-rests and the firing platform was
modified to take two ammunition boxes, one on each side.
A special seat was fitted to the top of the back of the
left-hand seat to give a higher sitting position for use
with the Mk 5 correctional sight.
