This Guide “glare-proof” day/night flip mirror is the type often seen on the better post-war GM cars. It appears that GM offered this special accessory through the late forties and early fifties for all makes and models in the line-up for these years. Due to their limited manufacture and fragile nature, not many have survived to the present day in good condition. Aside from some small blemishes in the original chrome, this one is in good overall shape for its age. The gold tinted anti-glare mirror flips in and out positively. Here’s an opportunity to get a rare original accessory that’s sure to be helpful when authenticity really counts in your next restoration or upgrade project.
