Hi Can some one help date this piece if possible.

I know it is Eloctroplate a that it can be difficult to date but I was wondering if the numbers have some thing to do with it. It is a Cooper Brothers Jug. It has the numbers 539 on the base.

With thanks

The numbers might aid dating - if only we had access to Coopers’ records. They are probably a pattern number or some other form of internal factory identification.
