WWII Royal Canadian Air Force Sterling Silver Sweetheart Wing

The wing is approximately 2-1/4 inches wide. The wing is fashioned in brilliant blue enamel with enamel in red, green and black as well. The enamel is without chips or cracks. The reverse is marked as 'Sterling', with a hallmark of 'J.A. & S.' and what appears to be the name of 'Kergo' scratched into the back of the wing in quite small letters. A beautiful wing in excellent condition.
