I have found some more images of the Swat Bowl, North-west India, 5th-6th century. Possibly of Huna or Kidarite cavalry (http://www.warfare.altervista.org/6-10/Central_Asia-117.htm): Two horse-archers hunting (http://www.warfare.altervista.org/6-10/Swat_Bowl-49.htm) and two horsemen with sword or spear, wearing crowns similar to the last Kidarite coins (http://www.warfare.altervista.org/6-10/Swat_Bowl-48.htm)
Note the apparently deformed skull, similar deformation can be seen on the Coins of Khingila, Alchon king, 5th century AD (http://www.warfare.altervista.org/Ancient/Khingila.htm) and earlier on the Armour Bearer, Khaltchayan Reception Hall, Yuezhi north Bactria, 50 BC-50 AD (http://www.warfare.altervista.org/Ancient/Khaltchayan-Armour_bearer.htm)
The pair of hairy objects on the rumps of two horses are plumes. They can be seen on a Sasanian Cameo of Shapur I vanquishing Emperor Valerian, 260 AD (http://www.warfare.altervista.org/Persia/Sasanian_Cameo_of_Shapur_and_Valerian.htm), details of their attachment can be seen on The "Stroganov Plate" (or Freer Shapur plate) with a Sasanian King hunting boar, Iran, 4th century AD (http://www.warfare.altervista.org/Ancient/Stroganov_plate-lg.htm). These plumes can be seen as late as the 7th century A.D on the "Sackler Plate" with a Sasanian King Hunting Ibex (http://www.warfare.altervista.org/6-10/Sackler_plate.htm). Similar plumes with flat rather than pointed end can be seen on a Sasanian plate of Shapur II hunting, fourth century AD (http://www.warfare.altervista.org/Ancient/Central_Asia-75.htm) and later on a Sasanian (or Umayyad) Horseman on a stucco panel, ca. 6th–7th century A.D.
