Cirencester Ginger Beer

[Cirencester UK]

I am looking for a Parry and Son , Grocer , Cirencester , Crown Top Ginger Beer. I know some come out of the Cirecester tip last year and will be digging there later this year but need one now to swop for an even rarer Cirencester GB .
Perhaps theres one out side of the UK , TOP PRICE PAID. or good swap.
