Birkin hac 31 barenia and toile

Super rare, I got it on Vestiaire and it’s authenticated through them. Blind stamp said circle W It’s about 20 year old vintage. I’ll add a blind stamp later. I also just spent 700 usd through rego brothers to clean and retouch the corners and scratches. It didn’t come with keys and lock, just came with a Vestiaire bag.
