Ok thank you.These are all typical heraldic symbols (heraldry is a hobby of mine). Pictured above on the stone tablet is a true "Cross Maltese". Adrian's crosses are both examples of "Cross Patee", with the Eisernes Kreutz simply being a Cross Patee with a type of embellishment called, variously, an orle or a tressure (this example is probably an orle, as a tressure tends to be quite narrow...really just a line).
