Description

Vintage 1930's 1940's Clamp On Side Mirror
Chrome was buffed over to give a better idea of condition
.
Overall in great shape. Very minimal pitting. Few light scratches.
Actual mirror size is 4-1/4" / Arm is approx 6" from base to mirror, but only comes out about 4".
I see no name or markings of any kind.
The correct
screw
that mounts the base to the arm is missing.
