I have recently obtained a vintage Conoco service station uniform from the 50's, I plan on displaying it on a mannequin, I will be adding a coin changer, and someone told me they remember the attendants carrying a window cleaner bottle. The only thing I have seen in books is a chrome cylinder bottle, but they remembered a bottle that was similar to a whiskey flask carried in the back pocket? What did they use in the 1950s, and did Conoco issue thier own equipment, or was it generic, any information would be useful, as I would like to display this as acurate as possible.also I only have the hat cover, and if anyone has the actual hat I may be interested in buying it, Thanks
