"Korwin I sometimes known as Ślepowron variation - In a red field, a black raven is facing left with a gold ring in its beak; it stands on a natural tree-stump, lying crosswise with two knots on top and two on the bottom. Over the helmet and the coronet are three ostrich feathers.
It’s one of the oldest Polish coats of arms, but neither Długosz nor official records from the fifteenth century tell about it. Prof. Małecki writes this coat of arms is separated from the Ślepowron only in the first decades of the sixteenth century (at the beginning, only Paprocki treated these two heraldic emblems as separates). Proof this fact some families that later used Korwin coat of arms but in the fifteenth century were still considered to be in Ślepowron clan, (Kochanowski family, for example). The name Ślepowron referred to the emblem, and the battle cry or call was Bojno or Bujno, as it’s proved in official records. Korwin coat of arms, being a later emblem, had no call."

"Korwin II – Reversing the figures is a common tool in Polish heraldry, which doesn’t follow the general principles of the Western heraldry; there is also an inverted Korwin facing right (instead of the usual drawing facing left). Niesiecki himself mentions it."

"Korwin III – In a red field there is a black raven with a gold ring in its beak, over a cut stump lying across, between two knots on each side. Above the helmet and the coronet there is the same raven with a ring. There are similarities between the crest of this variation and the crest of Ślepowron coat of arms."
