French vehicles

Grosser Funk und Beobachtungspanzer auf Lorraine-Schlepper 37L(f)
(translated is Large radio and observation tank on Lorraine tug 37L(f))

Conversion to artillery command post and observation for artillery on the chassis of the original French artillery tractor Lorraine 37L. On the chassis, is a new body of armour plates, machine gun, radio equipment and artillery sight.

The inventive military engineer Oberstleutnant Alfred Becker developed several mobile artillery vehicles that wreaked havoc on the Allies

The machines were put to work in self-propelled artillery units and the SPG's were converted to the same platform ( 10.5 cm leFH18/40 auf GW Lorraine Schlepper (f) and 15 cm sFH13 / 1 aus GW Lorraine Schlepper (f) ).
