Spare Tire Mounted Rearview Mirror. This is a heavy duty mirror! Probably weighs 1-1/2 pounds. Really solid. Chrome is really good, I cleaned it but it can get cleaner. I tried to find a manufacterer but it is unbranded. I feel like with the patina and solid maufacture, it had to have been manufactured in the 50's or earlier. Was it Ford, Chrysler, Pontiac, Duesenburg, I dont know! Put it on your car or truck and it will look swell! You'll be the bees knees! Any questions feel free to ask, thank you!
