Authentic Vintage Burberry Bag

My father-in-law used to work at the Burberry distribution center in NJ in the late 80's early 90's. I believe this was a sample bag so I'm suspecting there are very few of them. I cannot seem to find one anywhere on the internet. The bag has never been used. I have seen somewhat similar bags and I believe it's called a "Burberry Bowling Bag" but am unsure. I can provide additional pictures if you are interested.
