I think that you are right about the G&B thing from the post. It does look at the side with the place where the crank handle should be like my old G&B on the side. Was looking at it today also and could see under the green General Petroleum paint the light green and red diamonds of Associated Gasoline colors like I have in an old ad. Same size and colors. I have a picture of the insides, but do not know how to post them here in a reply comment section. Thanks to all for the info, and I am going to use the color scheme on a pump.
