1945 silver box variant, nameplate Serial Number 106856, Set ID 1174. For some reason, a few Fireflies have factory original silver paint on the outside of the box and inside of the lid. Perhaps a small group of these were painted under special orders. Or maybe the factory simply ran out of green paint for a short time.
