1972 Volkswagen Euro 1302S Super Beetle Deluxe
The front suspension on you 56 is from a much later model. In 1956 the torsion bar tubes were round. This one is composed of stamped halves welded together. In 56 the part the disc is attached to did not have ball joints like this. The disc could be an original equipment disc since German or European VWs came with disc brakes in the 1960s. The stamped metal front suspension like yours was also used in Type 2 and Type 3 models. Some of the Type 4 also had this front suspension.
