Amazing Muslin Lined Hornback Crocodile Clutch

Authentic crocodile hide billfold 8 1/2” by 5” lined with Muslin fabric, most likely vintage and high grade. No labels. Some wear shown in photos in center section but could be the hide itself, not sure which. Beautiful patina and treated with leather conditioner. I’m guessing 1960’s or 1970’s and could be custom made due to lining.
