ok, the only name for the silver i have found could be a member of the Payne family (Payne & son) in London for that period, they still have a company so might be of help to you, as to the glass, a lot of glass companys sent pieces to be silver topped or edged, also individuals with a favourite piece which was damamged had silver collars put on to disguise minor chips, i know it's not much help, but some one else on the board might be of more help, at least the year and assay office is confirmed London 1904, BTW, silver collars where put on earlier pieces of glass too.
Hope iv'e been of some help ,
Sue.
