Color (code) information needed for 1948 Pontiac engine

[VintageFlathead 10]

Hi all,

I'm in the midst of an engine rebuild and we want to paint the engine in the original dark green.

Does anybody now a code for the color? And a supplier for that matter?

I've found pictures of the first Oldsmobile with a Hydramatic from MY 1940. It moved from the Willow Run factory

following the closing to the Delco Remy museum a few miles up the road.

I hope the colorscheme is correct. I haven't found any other useable material (photos, books or anything else).

So i'm going with it I guess.

Thanks!
