I have a set of old mirrors that were on a 1965 Jeep Wagoneer that I used to have. They are what were called "baby West Coast Mirrors" back in the day.
They are made of aluminum tubing and look fairly original style.
Consider them as they are real great for backing up a vehicle that has virtually no rear vision.
Mine are not for sale as I am planning on using them, but similiar ones should be around.
