I don't think these mirrors are new old stock, but they sure look like it. Not sure who manufactured these, but they remind me of early 1960's AMC mirrors. Certainly could go on just about any classic car. May have a pit or two. The mirror glass on one, has some faint lines in the silvering.
The other one is fine. Please see all twelve pictures.
