Just got this sauce lade.

To me, it doesn''t look very 'Scottish', but I haven't handled a lot of it, so would love some other opinions.

A bit of a mystery (partly because I can't find my Scottish Provincial Marks book!). Three marks, each punched twice. I thought it look like I and N, so maybe Inverness? And then the third stamp which looks more like a running fox than a lion.
Any help would be great.
Cheers,
Ben
