I am considering the purchase of a early 1900's Waterman eyedropper which has a Star nib.

Unfortunately, I have some reservations about the authenticity of that nib.

Would anyone have some photos of some Star nibs which they are willing to post? I know there was more than one style of the Star imprint and, in fact, there was at least one version where the Star replaced the breather hole.

All examples would be greatly appreciated so I can fully assess the authenticity of vintage Star nib currently up for sale.
I'd like to compare the nib I am considering with several photos of bonafide Star nibs.
