Thanks for asking. I'm not sure the answer will be allowed here by the moderator but here goes nothing.
The symbol is called a "herbaz" in Polish and the figure itself is "Odrowaz"; meaning "other side of the Oder"; the Oder being a river that ran between the border land of Bohemia and that of Poland, called "Little Poland".
It is a Norse "rune", symbolizing a horse-warrior.
In 1410 a warrior band came north into Lithuania to join the Polish-Lithuanian Commonwealth in defeating
the Germanic Teutonic knights
during the Battle of Grunwald.
This was the bands heraldic symbol. Land grants were given in what is now Belarus by Lithuania to those knights. My family still remains there to this day. The herbaz is shared by a dozen Polish families.
My family's personal recipe for kielbasa is like no other. It is Polish with a Lithuanian spice influence. We have always done it this way. Who knows
It could be 600 years old.
As an infant almost 75 years ago, my tiny hand was thrust into the pile of meat on the kitchen table, that was waiting to be stuffed for Christmas. I have had my hand in kielbasa making, every year since then.
This kielbasa is only done for Easter and Christmas.
