Badge worn by mortars

Hello group .... I am wondering if someone can help me out. I am trying to figure out what badge would have been worn by mortar men. My late uncle, who was KIA, was with HQ platoon and was in their 2 inch mortar crew. So is there such a light mortarman badge ?

This is the badge for a Light Mortarman. I am not sure whether both 2 and 3 inch mortars would qualify. Perhaps someone with more knowledge on the specifics of the badge can shed some light. Photo taken from Jean Bouchery's 'The Canadian Soldier in NW Europe'.

Thanks a bunch. Now I know what badge to look for.
