Frog purchased six ex-COMET moulds in 1956, and issued them under the Frog 'Comet Series' brand, the Skyknight was remoulded in dark blue as per the original Comet kit, whereas the Aurora examples were more often than not cast in light grey. Later re-issued by Addar (ex-Aurora employees) but the blue plastic was lighter, and translucent in places.

Beware re-boxed Addar examples masquerading as Frog or Comet kits.
