Is this an Egyptian mark?

I have what I believe to be an Egyptian pumice stone covered in hammered silver. There are two very small marks (1mm sq) which I can barely see and are hard to photograph. Are they Egyptian, real and what do they ‘say’?

Hello, in the photo you couldn’t see the hallmark very well. If you can get a better photo I believe someone can help you identify it. Egyptian silver during part of the 20th century followed an English standard, with 3 marks, making it possible to identify the place of manufacture, percentage of silver and year. Look this website:
