Help with Overlapping SM or MS hallmark on caster

[kinkakuji]

Hoping someone can help me with the following overlapping SM or MS England mark. Could not find any other marks on the piece.
Caster is paw footed with lion decoration.


Thank you for your time. Any input would be greatly appreciated :)
