READER Nicola Selby says her husband has dug up an old beer bottle while working in the garden.

It has a screw-type top and carries the name W Bolton & Sons.

The trade mark is WB in a shield and it gives the address as Blackburn Road, Bolton.

Nicola asks if there has ever been a brewery on Blackburn Road and she wonders how old the bottle might be.

Well, Nicola, I spent half an hour looking through old Tillotsons' Directories in our library and drew a blank.

Maybe there is somebody reading this who can solve the mystery.
