WWII Militaria

Hello,I am hoping to get some help on identifying what I believe to be some sort of old brass military item,guessing WWII.I have no idea what this is and would like to identify it.In the center where the insignia/logo is located unscrews and there is a small bowl area in there where it looks like sometheing would go.I looked up british and french coats of arms and found nothing,but believe it to be french or british,on the center piece it has"HONI SOIT QUI MAL Y PENSE",roughly translated "Shamed Be He Who Thinks Evil Of It",which is french but was also used by the british,this is all google info.In the pic you can see all the small holes surrounding the center,so I thought maybe some sort of heater or burner,I dont know.I am hoping someone spots this and can tell me what it is,I thank anyone and everyone for any info they may have in advance.

Thanks.

Good
