The m. Zgkw. 8t (Sd. Kfz. 7) was developed as towing vehicle for middle loads like the 8.8cm Flak, the 10cm s. K. 18 or the 15cm s. FH 18 - which can be seen on the photo. It was also used as recovery vehicle for light armoured vehicles.
The conclusion model of the Sd. Kfz. 7 of the type KM m 11 was made beginning in 1944. The complex rear superstructure was replaced by a simple platform made of wood which could be covered by a simple tarpaulin. The photo was made in November 1944.
