Found this Vintage M. Walker & Son Limited. (Green Bottle) Froghall Bridge, Warrington in the Sankey Brook in Earlestown. Quite damaged but salvaged.
The bottom of the bottle does not have a number but it does have the maker N & CO - which stands for Nuttal & Co, who were based initially at Thatto Heath and then Ravenhead. This bottle is probably from the Ravenhead glassworks as it is recorded that they made the green coloured bottles.
Had to get into the Sankey to get it, the last picture shows the bottle where is has lay for quite a while. Unknown how it got there, no pubs nearby.
