Silver Spoon Motif Unknown Help

British Silver Reading Silver Hallmarks
1

Afternoon, I came across a silver teaspoon made by Thomas Bradbury & Sons Ltd from Sheffield in 1950 I think going by hallmark.

I see the text “nisi frustra dominus” on it which I know what it means but the motif is very interesting the letter A with a hand torch behind it.

Anybody recognise the motif?
