I can tell you the provenance of this extraordinary vintage waistcoat but I don't know exactly what type of fur it is - despite having met the maker it was a question I never asked! The lady who made this is in her late 80s and worked as a dressmaker all her adult life. She made this for herself in the 1950s, a vintage car enthusiast she motored around in an open topped car which, back then was a big deal. In later life she continued to have an interest in vintage cars and so would take out this fur for special meetings.
It has been expertly made, the fur is paneled and although these can be felt, it's difficult to see the joins. The fur is light beige and gold with a darker brown striped effect, it is super soft and silky. I genuinely have no idea what kind of animal this belonged to. 
The lining is a polyester cotton blend, dark brown with a floral paisley pattern brought out in shades of pale blue and bronze. 
The waistcoat fastens at the front with hand created loops, the buttons themselves are small, ornate bronze style, all are present.
Regardless of your stance of real fur, as a vintage piece it would be a sin to discard this on the basis of it's origin as it has been in existence as a garment for over seventy years. I believe it deserves a new home with someone who will appreciate and find the beauty in it.
