Not a yard Lonewolf definately a dock although it is used by only one company as far as i know,
your right with J8 though. I’ll give it to ya
Its actually Ellesmere Port docks run by Edward Nicholson Ltd.
Lots of heavy stuff shipped out from here.
I wouldn’t mind, I was toying with Ellesmere Port but decided to go with Bromborough!! 
be careful Highwayman, you can be arrested or sectioned for toying with a small town !!!
