Name that mirror??

Ok, it has 3 mounting holes the 2 holes closest to the windshield are 2 3/8" center to center. The base is fairly square and the dimensions on it are 3 1/8 by 1 5/8.

**I am looking to sell this, so if anyone is interested. $30 plus the ride, it is in near mint shape. Only minor minor pitting on the swivel ball.
