My late grandma worked at a British munitions factory. So why did she have this bracelet with a symbol like THIS???

My British grandmother died before I was born. I inherited some of her belongings and was going through a box of her old things when I found this tiny bracelet. It’s a bit of a shock because it looks like it has a swastika on it. I do not think she was a Nazi. It also has a small flag on it with the letters "SHDG" and the word "monterosa." And if you need more information, I remember my grandfather served in the Canadian army in World War II and met her at a dance in Britain while she was working at an ammunitions factory. I am just hoping that I can find out what this is and figure out why she might have had it. I am really hoping someone out there can help me solve this mystery. #FamilyHistory #WWII #Jewelry #Mystery #Swastika #HelpNeeded #Jewelry #FamilySecrets #FamilyStories
