What does this symbol on my rangemaster mean?

[BasementIdeas]

Hi

i recently moved and have a rangemaster double oven. Does anyone know what this symbol means? Google isn’t yielding much

thanks

I’d say grill but that’s a guess

Heated above and below?

I'd say top and bottom element heat. Grill is usually a zigzag line

There’s a separate sign for grill. Ok, that makes sense on hearing top and bottom
