Just to add some more confusion to this thread. This was posted this morning on Ebay. The notch looks different and the end piece looks like it has age, as the edges are softer. OP's pics show sharper edges. Newer or are they NOS?

If you don't mind being asked, what is the asking price of the ends?.
