unknown silver mark????

ive just got a small silver cup holder and cant find the marks anywhere,they are a picture of a sun with a face, .925 and the letter k,the maker is CB & S. anybody any ideas

We need to see a picture, but I am pretty sure that the marks are London import marks for 1905. The sponsor may be Charles Boyton & Sons, but I can’t confirm that until I see the hallmark.

thankyou for the info, i will send a picture but will have to wait for my daughter to do it as i cant upload pics yet. still learning.
