Very Good Original vintage Mirror for 50's 60's 70's cars / trucks/ Hot Rods/ Restoration and  more!
I am not a old parts expert by any means but my mechanic friend says these are really cool and highly sought after . 
I did not polish them up.  I see no rust. be sure to carefully look at pictures as these are also part of our description, what you see is how I unpacked them. Found in an Old barn in western NY.  Been in rafters at least 50 years. See the other mirrors and trim I have also on auction.
