Vintage ultra rare 1940s British Dispatch Rider Coat WWII

Vintage ultra rare 1940s British Dispatch Rider Coat WWII. Probably the coolest vintage piece I've ever owned, but I was never brave enough to wear it so I'm selling it to someone who hopefully is. The fabric is a super dense canvas material that feels bullet proof. For its age, the jacket is in almost pristine condition given its almost 100 years old at this point. I have yet to see another one in a similar condition that wasn't a remake. Average price online tends to be around 1000 usd. It's a single size so I'm not entirely sure how to describe the fit.
