Hallmark help think its silver

is anyone able to help me with these hallmarks, have 3 items all with the same markings ?

thanks in advance for anyone’s help

By a strange coincidence I was contacted by someone just a few days ago asking about this set of marks, but theirs was on a cigarette case. The 4 letters to the right are EPNS - standing for electroplated nickel silver, so this is not silver. The manufacturer’s mark has been identified here as “Granger & Campbell (possibly)”. However I doubt this identification as G&C were bagpipe makers.
