This is a replacement new cap, Blau brand, old made in Germany. It is the same size and shape as the original 1972 oil tank cap, it’s just missing the “OIL” stamp, there are decals available now. Good replacement but not concours perfect, but who will know at this point. I opened it to verify it would fit on a 72 tank, it is new - never used, opened packaging included.
