Hallmark ID - 19th century Jug

[lucys4452]

I can't seem to identify the hallmark on this jug, I would appreciate some information on when and where it was produced if anyone knows! Thank you.

Hi,

Welcome to the Forum.

Deykin & Sons of Birmingham. See: https://www.925-1000.com/silverplate_D2.html

Strictly speaking, it is not a hallmark, but a maker's mark only.
