Here are a couple pics of a (45+ year old NOS?) inflator bottle. scope

Compare the blue on the label with "USPS blue" on the box & "Corporation blue" on the '67 Valiant price guide.

There is a wide fade line vertically thru the middle of the price guide (& it's 48+ years old), but I'd bet the original spec. of the printing on the inflator bottle label was "Corporation blue".
