Need help valuing candelabra

I have a pair of candelabra which I want to sell but I dont know where to start. I have looked at the Antique price guide books but it doesn’t really help and I don’t really want to send them to auction. I’ll probably take them to an antique silver dealer but before doing that I’d really like to have a ballpark figure so that I know what to expect. They are Edwardian (1906) - sterling silver. The hallmark is shown on the attached photo and the maker is C&S & Co Ltd which I believe is London. They are inscribed J.B.W & M.C.W. They are approximately 40 cm high and 30cm wide. They have weighted bases, however some the packing material in one of them has come out and it weighs 1.982 kg. The other one is intact and it weighs 2.652 kg. Apart from the missing packing material that they are excellent conditiont.

I’ve been trying (without success) to upload my pic but this is the link to pic resize
