RCAF Reserve WWII service badge made by Birks

This is a fine small screw-back badge made by Birks for members of the RCAF Reserve during WWII. Measures just under an inch across, including wings. Marked Birks on the pin and DMW Pat. 1858686 on the screw back. These badges were made to last, and this one is in great, like-new shape. For some official information: https://www.veterans.gc.ca/eng/remembrance/medals-decorations/details/31 I'm cross posting this listing as I think it's general neutral.
