This example of Douro Silver does come with an associated name though, T&F Wright, Dover(UK). There is information about T&F Wright. My speculation on them was they were just the retailer and not the manufacturer of electroplated items. I was surprised however that T&F Wright were not retailing jewellers. My second choice however was ironmongers.

Trade directory entries in the early part of the 20th appear then to show another “Wright” ironmongers in Dover to compete with T&F Wright. Was this John James Wright again in another family concern?

Thomas P. Wright and Frederick G. Wright then were T&F Wright but, regarding Douro Silver, if anyone has seen the mark, did it have any other names associated with it?
