The Bowdon Downs Potato

Apart from a mention on the Altrincham History Society websites tour of Altrincham when it talks about one of the residents of Goose Green, “James Smith who was a bobbin-turner and grew early Bowdon Downs potatoes” (there’s that word early again!), we cannot find a mention of this potato and have not heard from a single soul – so we’re afraid extinction is looking like a grim possibility - unless you know otherwise?
