I'd like to know if it is grammatical to describe something as covered with "an animal", implying that the cover is that animal's skin, hide, etc.
I've found examples for an alligator's skin:
[The watch] has a thick rubber strap, covered with alligator and very much in keeping with the brand’s philosophy of fusion. (source).
[The loafers have] a vamp covered with Alligator. (source)
The first [Chatelaine] is sterling, covered with alligator. (source)
But are these grammatical?
