Rodgers star & cross razor

[pyril]

I recently aquired this and wanted to show. Maybe someone can tell me a little more about this blade. NOTE: I do not want this valued by any means. Just sharing, and maybe someone can provide some more details of it.
What I know: Rodgers Star & Cross razor, No 1. Looks like some of the white strip on the side is missing (pic attached). It's in the original box that it was given to someone in. On one side of the box, it says with compliments of The Neptune Oil Co Ltd, Sydney. This company started in 1909, and was sold in 1925 to the Lever Brothers. Someone has written a name on the box ( C. Miller), I don't know who this is. Other than what I can see, I know nothing of the blade itself, which is really what I'm hoping to find something of. The blade has been inscribed on one side 'use Warratah Motor Spirit' .
