Driver's manual flag-mount mirror can be installed on any '80-96 door. The pointers indicate small specks of something black on the chrome, like tar maybe. I suspect it'll come off easily with solvent. Also note the scars on the L side of the mirror head.
See these photos for installing it on a door that originally had a different type of mirror.
