In order to provide anti-tank support against the technically superior British armored forces, the availability of captured British vehicles from spring of 1941 on led to fitting at least 28 Morris-Commercial CS8 4x2 trucks with Italian 65/17 guns.
The original cargo bodies on the Morris trucks were modified by lengthening and by adding four topside panels that were hinged to allow the gun to traverse and recoil while firing to the side of the vehicle.
The first self-propelled guns were ready by September 8,1941 and a complete battery on 22nd of the same month.
Ultimately, some 7 improvised batteries were equipped with 65mm, providing a testament to the ingenuity and adaptability of the field deployed Italian units and their supporting field depots.
Each battery generally had four 15 CWT Morris CSS camionette armed with the Italian 65/17 gun, each with 36 rounds, and two ammunition-carrier camionette, each with an additional 250 rounds (half AT and half HE).
Some batteries were organized with three Morris gun trucks and two Ford F 15s with 20mm Breda cannons.
The batterie volanti ("flying battery") were a nasty surprise for the Allied opponents and performed well until their destruction thru enemy or - sometimes - "friendly fire".
