Brodie helmet insignia?

[SVT40]

Hello,

I have a Brodie helmet that has an insignia painted on that I can't locate any information on. I hope someone can help me -- I HAVE LOOKED EVERYWHERE!! I am still lokking through this site but so far no luck and there is a lot to dig through. I'm not even a hundred percent sure this is a British or Commonwealth insignia but I think it is. It is a Red shield with I think a white Acorn branch or oak leaf branch painted in white. It looks like it has been painted over something as well -- maybe a white shield. Any help would be appreciated. Thanks.
