Did Veltex actually have this grade of gasoline and logo?
Yes they did, they cheaped out and used decaled flat glass for both the Aviation Ethyl and for Veltex Ethyl globes (in two color variations), as well as used the decals on the pumps. I have pictures of both logos at stations.
I hope these are visible, it took a bit of effort and high dpi scans to extract these from small original photos. I'm pretty sure they are Idaho locations, but it would take some digging to say where. I'm posting these images as info for the forum, not for copy, I own these so please respect that, thanks much
