Anhänger (1achs) für Zubehör- und Munition für 3,7cm-Flak 36 (Sfl.)
Trailer (1-axled) for accessory and ammunition for 3.7cm AA gun 36 (Spg.)
Note: Sd. Ah. 57 features: Flat roof structure, no boxes on fenders and 2 hinges on panel.
The Sd. Ah. 57 was typically used with the vehicle: Self propelled (Sd. Kfz. 7/2) 3.7cm Flak 36 on chassis of the m. Zgkw. 8t. However one image [Ref Image 1119] shows the Sd. Ah. 57 trailer with Self propelled (Sd. Kfz. 7/1) 2cm FlakV 38 on chassis of the m. Zgkw. 8t. [Perhaps the storage compartments had space for either 2cm or 3.7cm magazines and it matters not if the Sd. Ah. 56 or 57 was used].
