The Basics... Identification Help - What is it?

Can anyone help identify this mark? Unfortunately, its right where the ding in the rim is so photos aren’t great. In the little box after sterling it says s then a large L then ltd. The L looks like the english pound L without the horizontal strike on the stem. My best guess in my research is Lipman brothers/Lipman-Levinter of Toronto but i have low confidence in my guess

Yes, thanks. I saw that too. The L is right but mine doesn’t have “bros” or the old Canadian silver mark. I’m wondering if it is the mark for the later Lipman-Trevinter but I can’t find a mark for that firm.
