60s Style Fondue Plates Makers Mark ID Help

Hello, does anyone recognise this makers mark? I believe it says 7 SN but can't find any reference to that online. I've seen these same dishes described as French but no maker was mentioned. Thank you :)

The continental 7 does suggest French, though even Denby made them.
I always thought these were maybe nut or sweetmeat dishes.

Thanks denbydump, I didn't know what they were, but when I searched divided dish it seemed this style was referred to as fondue plates - imagine they were used much more for nuts and nibbles though!
