Jeremy Croffs in his Templars Chart and Hieroglyphic Monitor (1821) has a “Order of Knights Templar Plan of Encampment”. It it are three banners. The one on the left, has a Templar Cross and a Lamb of God; the one in the middle a Blazing Cross; and then there is the one above. You see a cock sitting on what appears to be a metal ring, with weapons (and a trumpet?) sticking out of it. The odd design has a weird likeness to a symbol that can be found on the Kirkwall Scroll.
