Anyone know what HSL hallmark or JD&S trumpet means plea

i haven’t set my camera up yet but will do so. For the moment, I have a teapot, coffee pot, milk and sugar bowl all epns, very heavy and marked with HSL in capital letters within a square border under each piece.

I also have some beautiful silver spoons that have an old english style writing with JD&S with a trumpet.

Any help on what they are and the value would be really helpful. I would like to sell them.

many thanks,

I don’t know HSL, but JD&S + trumpet is a silver plate mark of James Dixon & Sons of Sheffield. Silver plate / electroplate has little commercial value so you may be best advised to keep and use the items.
