I found this interior paint from a previous post here. The actual link to the 1958 color bulletin is:

http://1954advance-design.com/Docum...2%20DuPont/slides/101958DupontB30S6.html

I took this information to my paint guy who could not come up with anything using the DUCO number (91623). He didn't know what DUCO was.

On the bulletin, there are two different kinds of numbers used down in the interior color section: "stock order number" and "formula file number".

Does anyone has any more information about this color, such as any other numbers, etc. Also, would this have been a likely color for the interior of my 58 Apache 1/2 ton big window short stepside? Has anyone found and used this color on the interior of their truck? Are there any pictures of this interior color? Thanks for the help
