Help to id potter’s SM mark - possibly Martin Silber

Hi All, Apologies. I’m new here. I tried to attach my photos but was unsuccessful. Here goes

Hi, the pix have loaded ok now. Looks an interesting bowl.
Could you possibly post a pic of the inside also.

Martin Silber maybe? But the top & bottom of the S doesn't curl as much as M Silber does. Don't know if his marks changed over time.

Thank you.
