Possible Old Mappin & Webb mark?

[AverilB]

Although fairly indistinct - could this mark possibly be Mappin & Webb? I have seen something similar in my investigations but not including the S&L script in the shield to the right.

Hi,
Two Mappin & Webb marks to confirm your attribution.
S&L is believed to mean Sheffield and London.

Excellent - thank you for your swift response.
