I have just picked up 3 sets of RAF wings. I know nothing about such items and would like to know if at least one of them is ww2. I know there are Kings and Queens crowns but really don't know the difference. I am sort of hoping the one with the writing is ww.2 as it is a nice little touch. I don't collect such items and will be listing them for sale in the sales section when I at least know whats what. Any help is much appreciated.
