My Gilbarco pump 's model number is 996 1ls and its serial number is 35303.. is there anyone that can help find information on it?

According to my Blue Book, the SN range for Gilbarco model 996 is from 29713 to 46404 in 1950, so if the production was consistent for the entire year, I am guessing April or May 1950.

Thank you very much... is there a way find the gas station it was used at and a photo of that station?

Chevron had a long relationship with G&B, so with the colors & decal, it is possible that it was indeed a Chevron pump. If that is original paint and decal, it is not a California pump, because there is not a "Tax" decal on it.

It was a Chevron pump.. unfortunately there wasnt much left of the original paint except for the chevron logo area and a few tiny slivers of green, red, and blue.. it had been painted over a bunch of times before i painted it... i believe original it was a Chevron Supreme pump due to the real tiny bit of green paint, then eventually was turned into a Chevron regular pump...
