The radio source B2 1320+299 is associated with a 20m QSO. Apart from the core component, it has two outer components on the same side of the QSO; it was therefore classified as of the one-sided (‘D2’) type. The radio structure is unusual in that the three slightly non-collinear components are apparently unconnected and the projected linear size for any plausible redshift is large for a ‘D2’ source (Feretti et al. 1982, Astron. Astrophys.115, 423). The radio structure has now been mapped with the VLA (λ20 & 6 cm, B array and λ20, 6 & 2 cm, A array; Figs.1a, b).
