I have been searching high and low for the center piece for a breast collar. I know I can use a plain ring, or a triangular 'ring', but I am looking specifically for the type of triangular piece that has two slots in the top where the shoulder pieces attach and a slot in the bottom for the lower cinch strap. Something like Jeremiah Watt makes, only plain, no engraving. Please help!! Thanks in advance for any direction in finding the illusive....
