Marianne Mödlinger and Christos Tsirogiannis have published a study of armour. It includes a group of 'armor for horses' (inv. 83.AC.7.1–2, 3–4) and two helmets (inv. 83.AC.8.1–2), all placed in 'Southern Italy'. The pieces were purchased from Antike Kunst Palladion in 1983. All six objects appear in the same image from the seized Becchina archive.
It is suggested, "the repatriation of these human and horse armour objects to Italy is the least that the Getty Museum should do".
