help with imported silver marks

[tyvm30]

it comes from a silver watch case, but was imported, i only know its 0.925 silver, glasgow, but what is "R.D.C", "T.F.S"? and what the date letter "d" means? i saw some date letter but with different shape.



what is "thos.fattorini ltd"? is it a english company? i thought it was a swiss movement, or its just a imported case with english movement.
