That is a coat of arms, of an armigious family, that I have not identified, yet, I may later, but am going to explain the tale of the shield/banner
for you now.
Starting from the top, ever wonder were that saying came from? Perhaps this is it...
The crown signifies royaly, most likely a king.
Ornaments which sit on the helm or crown in this case (as most often there is always a knights helm there on the shield instead, with a crown a top
it), are significant as not all crests will have such additions. This one is the Vol (Set of Wings), swiftness and protection. Usually an animal such
as a hound or K9 of some sort is there, to represent loyalty.
The shield and it's colors are most important, they are the base of the hereldry. Gold, means generosity, and is also mostly used my royal, or
esteemed family. Red, represents warrior or martyr, often times this is a very common color, but one or the other can only be known for sure depending
on historical accounts. Silver or White, peace and sincerity.
Placement of symbols should have a valid purpose for placement combinations. These designs are often well thought out with purpose.
Left side, red, "Head (Human)", honour, if the head of a "blackamoor" or Moor, refers to deeds of prowess in the Crusades.
Trumpet or horn, ready for war. The last, from what I can tell and beleive it to be, is crow, courage and perseverance, hero, able man in politics.
That is the translation of that crest for what I kow it to be. The other decorations, are usually just that, simple flair to add highlights.
