Vintage Bottle (Bromley BR2)

Anybody collect old bottles?
This was washed up on the south coast intact. I’ve not being able to find out what it is. It’s not a vintage Lucozade bottle as they never did one that had dimples all over. This is dimpled apart from a small square where the label would go collect the BR2 Bromley common.
