Since 1938, within the
Royal Italian Army, there was emerging a requirement for a transport vehicle for the troops and for the
Bersaglieri infantry regiments of the
armored divisions. The
Viberti introduced since in 1941 a prototype based on the SPA Dovunque 35 truck, however, technical doubts (the excessive weight of the armor on the chassis) and doctrinal questions on the use of such vehicle not turned the project into a contract. The prototype remained in Viberti workshops until 11 November 1944, when it was requisitioned by the Black Brigade
Ather Capelli of
Turin. Meanwhile, in 1942 the final version was set, with the top of the transport compartment covered. With the pressure of events in April 1945, the samples still being built at Viberti workshops, both covered top version and uncovered, were requisitioned by the various factions. At least three were taken by Republicans of the Social Republic. Two vehicles were captured by the
Italian partisans, one was destroyed by a
Panzerfaust from a legionary of the
29th Waffen Grenadier Division of the SS (italienische Nr. 1) (the Italian
SS division). == Description ==
