1948 Chevrolet Left Side Mirror

Description

You are viewing a used, vintage 1948 Chevrolet Van Mirror for the left-hand driver's side.
This mirror came off my grandfather's Chevy van that he used when he was employed by Standard Furniture in Seattle, WA.
The mirror is functional. The rubber grommet around the glass is in tact, as is the dark colored glass. There are a few spots on the mirror that look like rust. I think this is under the glass portion of the mirror.
The color is a dark green. There is also a number on the bottom of the mirror. As I read it, it looks like BTC 3684883, but I'm not positive.
Dimensions are as follows:
Length is about 13" (33.02cm).
Diameter of the round mirror is about 5" (12.7cm)
Any questions, please email me and I will do my best to answer them.
Thank you.
