Driver's side mirror with Heated and Thermometer options, original OEM option for the 1978 and 1979 Continental body style cars (Town Coupe, Town Car).  You would have to add wiring for the bulb, but it will also work with earlier 70's Lincolns.

It has a few tiny rock chips on front of the mirror hood.   The thermometer dial is stuck, but I'm including a replacement thermometer from a later model car that has degrees F and C on the dial, and it works well.   Mirror glass adjustment from the joystick works fine also.
