Hi Guys. Newbie to gas pumps. My uncle has a Chevron Supreme Original Gas pump that he wants me to sell and I am trying to figure out it's valuation.
Here are some pictures.

I am not sure on mfc date. 40's - 50's I believe.
It's all original, except for the dome at the top which is a remake. It was completely refurbished a few years back.
I don't believe it actually works though.
There is 1 scratch at the bottom that I forgot to take a picture of, but otherwise in immaculate condition.
The plate on the side reads:
Golbarco Calco Meter
Model # 96C138L
Serial # H3930
I tried to find a reference for determing the year but could not find anything.
I did some research for resale on ebay and a few other places and it seems that most are remakes.
The originals seem to be fetching anywhere from 2500-5500.
Due to it's condition, I estimate it's worth around $4000-$6000. Am I close?
Any input would be greatly appreciated! Thanks!
