The radio structure of the giant radio source 3C 130 is interpreted in terms of the dynamical model of Blandford and Icke. The overall edge-darkened double structure of this 1.2 Mpc source is disfigured by several symmetric wiggles. Assuming that the wiggles are produced by orbital interaction between the parent galaxy and a nearby companion the radio structure of 3C 130 is well reproduced. The effects of buoyancy on the structure are also taken into account. Together with the observed wiggling, the model also predicts the widening of the source as a function of distance from the parent galaxy. The best fit orbital parameters require a jet velocity of ≡120 km s-1, an orbital period of ≡1.3×109yr and an age of ≡2×109yr for the radio source. They provide an additional indication for the existence of slow jets.
