help identifying maker

hi, I have two small silver enamelled dishes, probably salt dishes. not in great condition as the enamel is scratched and chipped inn places.

the only markings are 925, then an S in a calligpraphy style font, then a long mark, which looks a little like a trident with a bar through the middle, or maybe a toasting fork!

any help identifying the maker would be great.

thanks!
